Anil kumar1, Santosh Metgud2 1Post Graduate, 2Asst Prof, KLE University Institute of Physiotherapy
Results : In the present study, intra - group analysis showed that improved range of motion and functional outcome was statistically significant in all the three groups (p=0.0001) whereas considering the reliability and validity of Knee Outcome Survey Of Activity Daily Living Scale, the between group analysis revealed that Group C was significant as compared to Group A and Group B in knee range of motion and in functional outcome Group B was significant compared to Group A and C .
ABSTRACT
The knee is a complex, compound, condyloid variety of a synovial joint. It actually comprises three functional compartments: the femuro-patellar articulation consists of the patella, and the patellar groove on the
INTRODUCTION
Methods : The present randomized clinical trial was conducted among 45 participants which included both male and female symptomatic individuals between the age of 18 to 50 years with knee joint stiffness. Pre-interventional and post-interventional outcome measurements were taken in the form of Range Of Motion, KOSADLS.
Conclusion : In conclusion, the present randomized clinical trial provided evidence to support the physical therapy regimen in the form of continuous passive motion with joint mobilization in improving range of motion, improving functional performance in subjects with post operative knee joint stiffness.
Objectives : To determine the effect of continuous passive motion in treatment of knee joint stiffness. To determine the effect of joint mobilization in the treatment of knee joint stiffness. To determine the combined effectiveness of continuous passive motion and joint mobilization in the treatment of knee joint stiffness.
Incidence of fractures was 100 per 10,000 population for males and 81 per 10,000 population for females.
Below the age of 55 years of all fractures showed a higher incidence amongst males but amongst the over 55, there was consistent fall in male:female incidence ratio with some sites showing a striking female preponderance.3Continuouspassive motion (CPM) refers to passive motion performed by a mechanical device that moves a joint slowly and continuously through a controlled range of motion. CPM is effective in lessening the negative effects of joint immobilization and also improves the recovery rate and ROM after a variety of surgical procedures. It also prevents development of adhesions and contractures and thus prevents joint Stiffness. It also provides a stimulating effect on the healing of tendons and ligaments and enhances healing of incisions over the moving joint. 4 CPM is used

front of the femur through which it slides; and the medial and lateral femuro-tibial articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower leg.1 Knee injuries from trauma or overuse can cause pain, swelling and sometimes disability, short or long-term depending on how bad the injury is. Injuries can occur to the bones, the ligaments, the cartilage or the tendons.2
Study design: Randomized clinical trial.

day 01 and on day 21 in the study groups. Once all measurements obtained subjects was randomly allocated into 3 Groups viz. group A, Group B, and Group C. Final scores on the scale and range of motion was measured after 3 weeks of treatment and was then subjected to statistical analysis
The physiotherapist performed an anterior tibiofemoral glide on participant’s operative limb, the physiotherapist grasps the dorsal aspect of the participant’s proximal lower leg with one hand and holds it firmly against his body while placing his other hand over the dorsal lateral aspect of the tibia just distal to the knee joint. He passively moves the knee joint to the maximum available knee-extension ROM. He then glides the participant’s tibia in an anterior direction parallel to the surface of the femoral condoyle to the point where the resistance provided by the knee limited further movements. The mobilization was given for 10 repetitions for 5 times. Total duration lasted for 20 mins.
Sample size – Forty five (45) participants
Maitland techniques involve the application of passive and oscillatory movements to spinal, vertebral and peripheral joints to treat pain and stiffness of a mechanical nature. The techniques aim to restore motions of spin, glide and roll between joint surfaces and are graded according to their amplitude10
Participants of all the 3 Groups i.e.
•Total Knee
•Any local or systemic infection.
Posterior- Anterior glide
METHOD
•Ligament injuries of grade 1 and 2
•Age group between 18-50 years.
Study design is randomized clinical trial. Data was collected from KLES Dr. Prabhakar Kore Hospital , Belgaum. Study period of one year (Feb 2011 to Jan 2012).
Anterior-posterior glide
The patient was asked to rest supine on the treatment table with affected leg on CPM machine. The speed was kept constant, so that a full cycle lasts for 45 to 60 seconds. The treatment was given for 40 minutes daily in split sessions i.e 20 minutes in the morning and 20 minutes in the afternoon, supervised by physiotherapist. The range was adjusted individually and increased gradually by 10 degrees daily within participant’s limits of pain. CPM was given for 3weeks during which various parameters was monitored.

therapy was given as conventional treatment for a period of 15 minutes, 2 sessions/day for 3 weeks prior to the CPM and Joint mobilization.
Joint mobilization stimulates biological activity by moving synovial fluid, which brings nutrients to the avascular articular cartilage of the joint surfaces and intra-articular fibrocartilage of the menisci6. Atrophy of the articular cartilage begins soon after immobilization is imposed on joints7,8,9

Inclusion Criteria
Range of motion was measured with a Universal Goniometer and Physical function outcome measured by Knee outcome survey activities of daily living scale, a well validated, self-report, self-complete questionnaire was used.
physiotherapist grasps the dorsal aspect of the participant’s proximal lower leg with one hand and holds it firmly against his body while placing his other hand over the dorsal lateral aspect of the tibia just distal to the knee joint. He passively moves the knee joint to the maximum available knee-flexion ROM. He then glides the participant’s tibia in an posterior direction parallel to the surface of the femoral condoyle to the point where the resistance provided by the knee limited further movements. The mobilization was given for 10 repetitions for 5 times. Total duration lasted for 20 mins.
Statistical analysis for the present study was done manually as well as using the statistics software SPSS 13 version so as to verify the results obtained. For this purpose the data was entered into an excel spread sheet, tabulated and subjected to statistical analysis. Various statistical measures such as mean, standard deviation (SD) and test of significance such as paired sample test for within group analysis and between group analysis was done with Multiple Scheffe Test, ANOVA was used for age and demographic distribution.

al, showed that in patients with supracondylar fracture, mobilization and exercise led to a greater increase in joint movement than exercise alone. The present study is in consistent with the above study as the results concluded the same. Hence the effect of joint mobilization has an effect in increasing range of motion17.Michael

investigator-blinded RCT compared three rehabilitation regimens in patients who had undergone primary TKA for osteoarthritis. The results suggest that adjunct CPM and adjunct SB may not provide additional therapeutic benefit in an active mobilization regimen following TKA for osteoarthritis. Hence the present study consistent with the above study as the result concluded the same. The study done by Beaupre et. al., hypothesized that continuous passive motion may not provide therapeutic effect in active mobilization of post-operative knee stiffness.15Inthe
The results of the present study group receiving CPM, has shown that alone CPM is not a beneficial method to mobilize post-operative knee stiffness. As suggested by Bearpre et. al., (2001), a prospective,
age in the present study was 34.82, ranging from 18-50 years. When compared between the three groups showed equal distribution and has no statistically significant difference in age between the group. A study conducted by Peter J. Millett(2004) has taken the age group of 18-57 years with average of total participants was 35.6, which coincides with the present data.11Macrae
In the present study the application of moist heat for 15 mins in all three groups prior to CPM and joint mobilization showed increase in range of motion. Knight et al. Investigated the effect of 15 min hot pack application paired with static stretching on plantar flexor extensibility over four weeks and noted increases in range of motion. These findings suggest that hot pack application may be a beneficial modality when increased range of motion is desired.14
and wright in 1969 showed a substantial difference in stiffness between male and female knee joint. Males are much stiffer than females even when age, size of thigh, and size of knee is taken into account. It is interesting to note that while this work shows that females are less stiff than males. The finding of this study correlates with the above reference since maximum number of patients was males, showing more stiffness than females. 12 Hutchinson M studied on gender difference in active knee joint stiffness concluded that females have reduced active stiffness compared to age matched males. The present study correlates with the above study in gender differences and has no effects on altering the results between the groups.13
present study, group receiving CPM only, showed an average increase in ROM for post operative knee stiffness of 49.733, which was less compared to the other 2 groups ie., group B-59.80 and group C-68.93. The present study correlates with the study done by Engstrom et al. (1995) reported on a prospective randomized study of 34 patients with unilateral anterior cruciate ligament ruptures. Engstrom et al concluded that after six weeks follow–up, there was no difference in ROM between the two groups, and joint swelling was more pronounced in the early active motion group. The data suggests that CPM did not improveRandallROM.16et
Study done by Mei Hwa Jan MS et al to investigate the effect of weight bearing exercises on function, pain and knee strength in patients with knee stiffness. The results showed that weight bearing exercises were effective in decreasing pain and disability and increasing knee strength.20
When the intra group mean values of active knee range of motion of flexion was analysed, it showed statistically significant improvement in knee flexion range of motion in both the groups pre to post intervention, with the p values of 0.000 in both the groups, but when comparison was done inter-group, group C showed more improvement in knee range of motion as compared to group A and B. In the present study increase in range of motion, with the application of continuous passive motion in one group and joint mobilization in another group is consistent with the findings of previous studies. This is the first study till date has compared the combined effect of continuous passive motion and joint mobilization. Present results showed that continuous passive motion with joint mobilization is better than giving individually.
A. Hunt, Stephen R. found the effect of anterior tibiofemoral glides on knee extension during gait in patients with decreased range of motion after anterior cruciate ligament reconstruction. The authors concluded that a single session of anterior tibiofemoral glides increases maximal knee extension during the stance phase of gait in patients with knee extension deficits. In the present study 21 sessions of mobilization increased maximal knee extension range of motion and could not comment on the immediate effect of joint mobilization18Inthepresent

CONCLUSION
The findings of the present study show that improving ROM by joint mobilization is effective which was due to stimulation of biological activity by moving synovial fluid, which brings nutrients to the avascular articular cartilage of the joint surfaces and intraarticular fibrocartilage of the menisci21.
The one-leg stance is a valid measure to assess postural steadiness in a static position by temporal measurement. The examination of balance with oneleg stance test is a functional and logical approach, since transient balancing on a single limb is essential for normal gait and critical activities of daily living such as turning, stair climbing and dressing and it is also essential for sports person who need good proprioception to be good in their field of sports.
Objective: The objective of this study is to compare the significant changes in Blood Pressure and Heart Rate in young college going males and females while standing on there dominant and non-dominant lower limb (single-leg stance).
Data Analysis: P-Value was calculated for the systolic and diastolic blood pressure separately and as well as of Heart Rate in resting, single-leg stance on dominant leg and single-leg stance on nondominant leg in both Males and Females.
1)Autonomic regulation mediated by sympathetic and parasympathetic responses, which affect heart
clinicians have continued to use single-leg stance manipulations for both the evaluation and rehabilitation of proprioceptive deficits related to orthopedic injury.
Human Heart rate can vary as the body’s need to absorb oxygen and excrete carbon dioxide changes, such as during exercise or sleep.
Conclusion: From The study it can be concluded that while training any individual on single -leg stance on dominant and non-dominant a therapist should take care of the blood pressure and Heart Rate specially while working on hypertensive's, amputees, individuals with cardio-vascular, neurological, psychological and neuro muscular disorders.

ABSTRACT
Keywords: Heart Rate, Blood Pressure
During rehabilitation, this method is used both for a baseline measurement of balance and to progress patients as they recover.
Short-term cardiovascular responses to postural change involve complex interactions between the autonomic nervous system, which regulates blood pressure, and cerebral auto regulation, which maintains cerebral perfusion. A physiologically based change is used to describe effects of gravity on venous blood pooling during postural change. Two types of control mechanisms are included:

7.Subjects are not involved in any physical or muscular activity in last one hour before testing.
SOURCE OF SUBJECTS - Students from various colleges in Delhi.
Static contraction of muscles on a large scale, e.g. with the knees bent as described, soon causes a remarkably large rise of systolic and diastolic bloodpressures, comparable to what may be induced by strenuous muscular exercise, but differing in certain respects in the mechanism of its production.

rate, cardiac contractility, resistance, and compliance, and
on Heart Rate are due to muscular activity changes when posture changes, abdominal wall tension increases while standing on single leg, the aortic pressure increases according to Marey’s law and also due to carotid sinus reflex.
The need of this study is to have a better understanding that how does Blood Pressure and Heart Rate changes in young individuals who are under going physiotherapy to increase their proprioception, balance and co-ordination, a hypertensive individual ,an individual using prosthesis or an amputee (any limb), an individual under going any cardio-vascular, neurological, psychological or neuro-muscular disorder when they stand on there single lower limb (dominant or non-dominant) and does the gender of the individual plays in any significant role in it.
It also seen that women have lower risks of cardiovascular events than men. They are also characterized by different spectral indexes of HRV24, and by higher HRV entropy25
1.BMI less than 18 and more than 25 kg/m2
The Blood Pressure and Heart Rate vary in respiratory, neurological, psychological and in cardiovascular disorders. BMI also plays a major role when it comes to one leg standing, the individuals with BMI more than of 25cm2/kg has a higher Blood Pressure and Heart Rate while standing on single leg.
METHODOLOGY
2)Auto regulation mediated by responses to local changes in myogenic tone, metabolic demand, and CO2 concentration, which affect cerebrovascular Theresistance.change
Assumption of the upright posture requires prompt physiological adaptation to gravity .There is an instantaneous descent of ~500 ml of blood from the thorax to the lower abdomen, buttocks, and legs. In addition, there is a 10-25% shift of plasma volume out of the vasculature and into the interstitial tissue. This shift decreases venous return to the heart, resulting in a transient decline in both arterial pressure and cardiac filling. This has the effect of reducing the pressure on the bar receptors, triggering a compensatory sympathetic activation that results in an increase in heart rate and systemic vasoconstriction (countering the initial decline in blood pressure). Hence, assumption of upright posture results in a 10-20 beat per minute increase in heart rate, a negligible change in systolic blood pressure, and a ~5 mmHg increase in diastolic blood pressure. Assumption of the upright posture requires prompt physiological adaptation to gravity.The response of blood pressure to change in body position is well suited as a measure of cardiovascular reactivity for epidemiological studies. Several experimental studies have suggested a differential response of blood pressure to standing due to ethnicity1 and gender2, 3
As it always seen that men have more muscle power as compared to women, indirect evidence indicates19,20 that women will experience less compressive force and intramuscular pressure in the muscle21,22,23, allowing greater perfusion and oxygen supply compared with the men during the sustained contraction during the change in posture.

Total of 265 subjects were taken out of which 200 subjects fulfilling the inclusion criteria and after checking that they had not gone for any vigorous physical or muscular activity in last one hour were taken into consideration. The procedure was explained to the subjects and a written consent was taken after explaining the benefits and clearing the doubts of the subject regarding study. To check the lower limb dominance subjects were asked to kick a football and the leg from which he/she kicked was considered as his/her dominant leg. After this subject’s BP and HR was taken while sitting on chair. They were given a rest period of 5 minutes then, they were made to stand on their dominant leg for a minute. After which their BP and HR was recorded in seated position, and they were made to rest for 5 minutes again. Post rest period the subjects were asked to stand on their non-dominant leg for a minute this time again their BP and HR were taken in seated position.

respective of the postural change, i.e. standing on dominant and non-dominant leg there was a significant increase in HR and decrease in BP. Although muscle activity increases body oxygen consumption and energy expenditure, the temporal increase in HR and decrease in BP associated with changing position suggests that it is likely to have resulted from the metabolic or hormonal consequences of increased muscle activity. We speculate that this increase was largely induced by the skeletal muscle reflex15-17. Although anticipation of exercise may also cause a rapid increase in heart rate18.

Variation of heart rate is associated with postural change26. In accord with previous reports, this study showed that HR was highest in standing on NonDominant leg compared to sitting or lying positions4-11 Thus, the hypothesised that the increase in HR with standing follows a decease in venous return due to “venous pooling” in the lower limbs due to gravitational effects12. The increase in peripheral venous volume is accompanied by an increase in both venous and arterial pressure in the lower extremities. The shift in blood volume from the central to the peripheral system induces a decrease in venous return and central venous pressure. The smaller the venous return, the smaller the end-diastolic and subsequent stroke volume. A reduction in venous return will lead to a reduced cardiac output, which in turn will lead to a reduction in baroreceptor stimulation in the aorta and carotid arteries13. This reduction in baroreceptor firing results in decreased parasympathetic and increased sympathetic activity14, 11. These two actions directly affect the cardiovascular centre in the medulla oblongata which increases the HR, the arteriolar and venous tones, and the cardiac contractility to compensate for the decrease in stroke volume and provide a cardiac output which can meet body demands. Upon returning the posture from sitting to lying, the increase in venous return increases the stroke volume through the Frank Starling mechanism, thus a lower heart rate is sufficient to maintain the cardiac output demanded by the body.

Conclusion: It can be concluded that High frequency TENS can be given to Diabetic Neuropathy patients for three weeks to achieve pain reduction.
DPN is often referred to as the forgotten complication because, despite how commonly it occurs, it is the chronic diabetes complication that is least often addressed by health care providers.15 Results of the 2005 American Diabetes Association (ADA) National Survey found that only one in four patients surveyed who experience symptoms of DPN have been diagnosed with the condition. 16 This is partly because many practitioners have had very little success with its treatment as well as a lack of awareness of available treatment strategies. A wide range of treatments are available for neuropathic pain, however, many patients remain inadequately treated. This prescribing pattern suggests that no one treatment addresses all factors. Foot complications are the greatest burden of all serious chronic complications among patients with diabetes.
Participants and Outcome Measure: 20 Patients with a diagnosis of Diabetic Neuropathy were included in the study and they were explained regarding the treatment & its duration. Outcome measures were recorded before & after the treatment session using numerical pain rating scale.
Design: Prospective Experimental Study.
Effectiveness of Transcutaneous Electrical Nerve Stimulator (TENS) in Reducing Neuropathic Pain in Patients with Diabetic Neuropathy
INTRODUCTION
A consequence of any neuropathy affecting motor and sensory peripheral nerves is reduction or loss of strength and sensation. Another potential consequence of peripheral neuropathy in people with diabetes is severe, unremitting pain.1, 4 People with painful diabetic neuropathy describe their pain as constant, burning, or searing. Allodynia, to light touch, the experience of light touch as painful, frequently develops, and even contact with bedclothes can be painful. Deep pain, described as being located in the centre or marrow of the bone, can also occur. When pain is severe, people
with diabetic neuropathy may have difficulty sleeping and can experience depression and weight loss.1
Objective: To evaluate the effectiveness of TENS in reducing neuropathic pain in patients with Diabetic Neuropathy.
Diabetes mellitus is caused by an insufficient insulin-mediated response to blood glucose. People with the disorder are classified as being insulin dependent (ie, having type I diabetes) or non-insulin dependent (ie, having type II diabetes) depending on whether they require exogenous insulin for survival. A frequent sequella of both types of diabetes is the development of peripheral neuropathy in either motor or sensory nerves, or both.1 Crawford2 estimated that 13 million people in the United States have diabetes, and 30% to 40% of these people are believed to have at least sensory neuropathy.3
ABSTRACT
Apeksha O. Yadav1, G. J. Ramteke2
Diabetic peripheral neuropathy (DPN) endoneurial hypoxemia – is the most common complication of diabetes, estimated to affect 50% to 90% of patients, depending on the criteria used for diagnosis 5-10. Its prevalence increases with the patient’s age, duration of diabetes, and poor glycemic control.11-14
Material and Methodology: This is a Prospective experimental study carried out in Physiotherapy OPD in Tertiary Care Hospital. Material used were TENS apparatus. 20 subjects were selected with a diagnosis of Diabetic Neuropathy. Both Males and Females were included. Patients recently underwent surgery for lower limb fracture with an implant and patients with pacemakers were excluded from the study. Study was explained to them & written consent was taken from them to undergo treatment for three weeks. Observations were recorded using numerical pain rating scale pre treatment i.e. 1week before the commencement of program and post treatment i.e. third week after the completion of treatment program. Patient was assessed before starting the treatment. Patient was made to lie in prone position and then the TENS electrodes were applied on the lumbar region with the use of aqua sonic gel. Frequency used was 80 Hertz. Duration of treatment was 20 mins daily for three weeks.
Dinesh Kumar, MD, Inderjeet S. Julka, MD, Michael S. Alvaro, DPM & Howard J. Marshall, DPM, did three independent studies utilizing TENS & amitriptyline to relieve DPN pain was reviewed. There were 14 patients in this group. Two of them did not tolerate amitriptyline. Symptomatic improvement occurred in 12 (85%) patients; 11 received the combination of amitriptyline and electrotherapy and 1 received electrotherapy only. Three patients improved by 3 pain grades, 8 by 2 grades, and 1 by 1 grade. Five (36%) of them experienced complete symptomatic relief.
& Somers in a case study stated that by using high frequency TENS for 20 minutes daily for 3 weeks over lumbar region relieves pain of neuropathy of a 73 years old lady the outcome were measured by the regular assessment and by using VAS as it is reliable and valid tool for the quantification of perceived pain, the intensity of perceived pain was reduced from 7.4 to 4.6 cm on the VAS and reduction of pain was gradual in given 3 weeks22
As many as 40% to 60% of lower-extremity amputations (LEAs) are related to DPN, and more than 50,000 LEAs are performed each year in this country. 17,18

Approximately 15% of patients with diabetes will develop a foot ulcer and one in six will need to have an amputation. Additionally, half of those patients who develop an ulcer will have one on the opposite foot within 3 years 19-21. Short of ulceration and amputation, DPN limits mobility, impairs sleep, and seriously affects overall QoL. It is a progressive disease that may actually begin before any alteration in sensation is detected.

Kesharia1, Amita Mehta2 1M.P.Th., Cardiovascular and Respiratory Sciences, 2Professor & Head, P.T. School and Centre, Seth G.S.M.C. and K.E.M. Hospital, Parel, Mumbai.
Results: There was a statistically significant improvement in PEFR, FEV1, RR and RPE in both the groups. However, there was no statistically significant difference in PEFR and FEV1 i.e. airway obstruction between the two groups. But, there was a statistically significant difference in RR and RPE i.e. dyspnea between the two groups, with breathing control showing greater improvement in dyspnea.
INTRODUCTION
Evaluation of effects of Nebulization and Breathing Control in Asthmatic Patients
Purpose: The purpose of our study was to evaluate the effects of nebulization and breathing control (N+B combination) as against only breathing control(B) on airway obstruction [by measuring peak expiratory flow rate(PEFR), forced expiratory volume in 1st second(FEV1) and dyspnea [by measuring respiratory rate (RR) and rate of perceived exertion (RPE)] in asthmatic patients.
Conclusion: Thus, asthmatic patients not only could reverse their airway obstruction (PEFR, FEV1) with Breathing control but also improved in terms of dyspnea (RR, RPE) as compared for Nebulization and Breathing control group. Nebulization and Breathing control group though it showed statistical significant improvement in airway obstruction(PEFR,FEV1) than only Breathing control; but the overall energy expenditure and thermogenic effect of nebulization with salbutamol did not help reverse dyspnea(RR and RPE)to the effect the breathing control could to.
Asthma is a problem world wide, with an estimated 300 million affected individuals. 1 The WHO has estimated that 15 million disability adjusted life years (DALY‘S) are lost annually due to asthma. Absence from school and days lost from work are substantial social & economic consequences of asthma in studies from India.1

Background: Asthma is a disease characterized by airflow limitation that is either fully or partially reversible. There is a growing realization that in asthma the airflow limitation leads to further mechanical consequences that result in dyspnea which is also a very important domain along-with airflow limitation to build up strategies to effectively cope up with asthma. To treat asthma effectively means to achieve a better level of control of asthma. Various strategies have been adopted by the patients themselves to keep their asthma level in control and avoid frequent exacerbations. Asthma has many dimensions to it rather than only airway obstruction. Asthma is affected by anxiety, cold, emotional quotient & also by the level to which other non- pharmacological means to control asthma adopted by the patient like yoga, meditation and various breathing strategies. It was seen that pharmacological measures though were very essential to treat asthma, but along-with its long term use; factors like adverse effects of medications, patient's non-compliance, cost effectiveness of treatment, patients sense of satisfaction of their disease control came into focus. Hence, various non-pharmacological measures were researched in the past trials, of which breathing control was one of the measures used.
In Asthma, the predominant feature clinically is episodic shortness of breath, physiologically episodic airway obstruction characterized by expiratory airflow limitation & pathologically airway inflammation, which persists even during the asymptomatic periods. Airway narrowing is the final common pathway leading to symptoms and physiological changes in asthma.

PROCEDURE
Starting position for both the groups-Patient sitting supported with back support and hip knee flexed and both hands placed just below the xiphisternum.
The study was approved by the ethics committee for research on human subjects (ECRHS) of the institute & written informed consent was taken from patients. Patients were assigned randomly in two groups by computer generated random number chart and given a 30 minutes session:
GROUP I: Asthmatic patients were given nebulization and all the factors affecting deposition of drug particles in the airways was taken into consideration.9 Asthmatic patients were nebulized using salbutamol (Asthalin) with saline in the ratio of 1:1 i.e. 2 ml of Asthalin in 2 ml of saline; with Pulmomist nebulizer in relaxed sitting position with head and neck adequately supported. Patients were asked to inhale the aerosol generated with a slight pause after inspiration9. Nebulization was given for 1 st 10 minutes and same patients were given breathing control for next 20 minutes (during which time the peak effect of nebulization was also reached). Patients were given Breathing control immediately by using8
Group I: Nebulization for 10 minutes and breathing control for 20 minutes.(N+B)
A 2000 systematic review of breathing techniques concluded that too few studies had been carried out to warrant firm judgments, but that collectively the data implied that physiotherapeutic breathing techniques may have some potential benefit4. A 2004 Cochrane review of breathing exercises for asthma concluded that, due to the diversity of breathing exercises and outcomes used, it was impossible to draw conclusions from the available evidence5.
in addition to pharmacological treatment & hence the above study was undertaken.
Group II: Breathing control for 30 minutes. (B)
Thus, various Physical therapy interventions aimed at overcoming dyspnea by overcoming early airway closure were chosen: Nebulization with selective B-2 sympathomimetic bronchodilator i.e. Salbutamol & Breathing control- wherein during inspiration normal tidal volume breaths are taken; with more effective use of diaphragm as it itself is an active inspiratory muscle during inspiration and during expiration, use of Pursed lip Breathing is emphasized.
Severity determines both the severity of the underlying disease and its responsiveness to treatment, but it may change over months or years. Therefore, periodic assessment of asthma control is more relevant and useful. Asthma is a growing problem with a huge economic burden. The annual cost of asthma to the NHS, constitutes about 83% i.e. Majority of it is due to medications. Accordingly, the development and evaluation of interventions to prevent asthma, to reduce its severity or improve its prognosis are the priority researches.2Pharmacotherapy is the mainstay of asthma management, but the outcomes remain suboptimal for complex reasons including under treatment and noncompliance. 3 Also, many patients have concerns about regular medications and many use nonpharmacological and complementary therapies including breathing modification techniques. 3 There has recently been renewed interest in the breathing techniques used in asthma. 3
A 2007 RCT demonstrated that breathing retraining and relaxation significantly reduced respiratory symptoms and improved health-related quality of life in a cohort of patients with asthma.6 A 2008 RCT adds further strong support to this work, also finding significant reduction in asthma symptoms.7
Methodology Study design- Experimental study- A Randomized controlled trial. Study settingPhysiotherapy department, Seth G.S.M.C and K.E.M.H, Mumbai. Sample size- 60 patients with asthma who satisfied the inclusion criteria were selected. Inclusion criteria- Clinically diagnosed asthmatics in the age group of 18-35 8 years, either sex included, who were referred for physiotherapy treatment. Exclusion criteriaAsthmatics with acute exacerbation in previous week1 Asthmatics with status asthmaticus 9 .

Duration of study-2010-11
Thus, it was important to understand the effect of physiotherapeutic techniques on dyspnea as a result of airway obstruction in asthmatic patients & to appropriately emphasize breathing control techniques

done by Kendrick, et al it was found that the Modified Borg’s Score(MBS) is a valid and reliable assessment tool for dyspnea and correlated well with other clinical parameters and could be useful when assessing and monitoring outcomes in patients with acute bronchospasm. In asthmatics, the mean MBS rating decreased from 5.1 at baseline to 2.4 after treatment. The mean PEFR increased from 286 at baseline to 414 after treatment. In the asthma group, there was a significant negative correlation between

All 30 patients in (N+B) and all 30 patients in (B) group responded and improved with intervention. Asthmatic patients showed statistically significant improvement in airway obstruction and dyspnea with nebulization and breathing control and with only breathing control also. There was no statistically significant difference between the groups in terms of airway obstruction as measured by PEFR and FEV1 .There was a statistically significant difference between the groups in terms of dyspnea as measured by RR and RPE. Breathing control is more effective to reduce dyspnea.

al, found that inhaled salbutamol significantly increases the resting metabolic rate of the patient due to thermogenic effects of salbutamol nebulization which may not effectively help to decrease the perceived exertion and thus respiratory rate13.The above may be one of the reasons why nebulization component may have added the energy expenditure and hence dyspnea in terms of RR and RPE. This also emphasizes that PLB in our study does not increase the energy cost of breathing as the dyspnea in terms of RR and RPE improve. By learning and understanding Breathing control, patients control their own breath, thus anxiety is also reduced; which is also one of the factors why they perceive less dyspnea.

overall Quality of life. Though, nebulization by B-2 agonists showed immediate improvement in asthma symptoms and lung function in terms of PEFR and FEV1. However, regular inhalation of B-2 agonists was associated with deterioration of asthma control and such trends in treatment may be an important causal factor in the worldwide increase in the morbidity from asthma. Whereas, when intervention with breathing control was performed not only was there immediate improvement in measures of PEFR and FEV1 and overall symptoms; but also studies support the view of regular use of breathing control techniques helps to achieve both the goals of treatment i.e. Decrease in overall manifestation of asthma and improve Quality of life. In view of all the above, breathing control is an important technique to intervene dyspnea along-with proper pharmacological treatment.

However, Lewis et al in a systematic review evaluated the short term effects on outcomes related to the mechanism of intervention and physiological outcomes. A beneficial effect was found for abdominal movement, diaphragm excursion, respiratory rate, tidal volume, arterial oxygen saturation. However, breathing control had a detrimental effect on the work of breathing and dyspnea. The study proposed that when used as a sole intervention, there was a beneficial effect on outcomes related to the mechanism of intervention and physiological outcomes. Only in people with severe respiratory disease, breathing control resulted in a detrimental effect on dyspnea and work of breathing. There was no clear evidence on gas exchange and energy cost of breathing14

change score in MBS & change scores in the PEFR from pre-scores to post-scores (r = -.31, P < .05). As the PEFR score increased, the MBS score decreased; thus the better the patients’ peak flow scores, the lower the patient’s dyspnea ratings12. Thus, the above may be one of the reasons the improvements in our study of decrease in airway obstruction and improvement in dyspnea go hand in Ambrosohand.et
Thus, the physiotherapeutic techniques used in various above studies helps control the symptoms of asthma and hence their manifestation. Also, most of the studies have evaluated the long term i.e. At least 1 month and 6 month results of lung function and overall asthma control; but immediate effects of breathing control were not studied. Thus, the improvements in lung function measures of PEFR and FEV1based on breathing control techniques suggest that there is immediate improvement in lung function measures.
Asthma is a chronic disease; the goal of treatment should be to decrease its overall manifestation and achieve a better level of control and hence improve the

Cerebral palsy is a well-recognized neurodevelopmental condition beginning in childhood & persisting throughout the lifespan. Cerebral palsy is a group of permanent disorders of the development of movement and posture, causing activity limitation, that are attributed to non-progressive disturbances that occurred in the developing fetal or infant brain. The motor disorders of cerebral palsy are often accompanied by disturbances of sensation, perception, cognition, communication, and behavior; by epilepsy, and by secondary musculoskeletal problems.1 Cerebral palsy is the commonest physical disability in childhood, occurring in 2.0 to 2.5 per 1000 live births.2 The causes are congenital, genetic, inflammatory, infections, anoxic, traumatic & metabolic. The injury to the developing brain may be prenatal, natal or postnatal.3 Causes of CP were prenatal in 50% of the cases, perinatal in 33%, postnatal in 10%, and mixed in 7%.4 75% of children with CP have spastic cerebral palsy. 3 Spasticity is classically defined as a tonal abnormality of skeletal muscle characterized by a velocity-dependent
Purpose: To determine the effectiveness of Neuromuscular electrical stimulation combined with Cryotherapy on spasticity and hand function in patients with spastic Cerebral Palsy. Children with CP often demonstrate poor hand function due to spasticity in wrist and finger flexors.
Results: Showed that both the group improved significantly but group A improved much better than group B.
Conclusions: This study suggests that NMES combined with cryotherapy is more effective as compared to cryotherapy alone in reducing spasticity and improving hand function in spastic CP patients.
Effect of Neuromuscular Electrical Stimulation Combined with Cryotherapy on Spasticity and Hand Function in Patients with Spastic Cerebral Palsy
Various treatment approaches & modalities to manage spasticity associated with spastic cerebral palsy include the use of oral neuropharmacological agents or injectable materials such as botulinum-A toxin7, surgical treatment through tendon transfer8 or selective rhizotomy 9 . The other treatment approaches are application of cryotherapy 10 , progressive resistive exercises to improve muscle strength, repetitive passive range of motion exercises to improve & maintain joint mobility. Passive, static, gentle stretches are performed on individual joints to decrease & prevent joint contractures. Neurodevelopmental treatment (NDT), sensory integration, electrical stimulation, constrained induced therapy & orthosis are also used in management of cerebral palsy.11, 12
Methodology: This was an experimental study of 30 spastic CP patients aged 5-15 yr with mild to moderate spasticity. All the subjects were divided into two groups (A & B) with equal subject number in each group. Group A were treated with passive stretching, cryotherapy followed by Neuromuscular Electrical Stimulation (NMES) and Group B treated with passive stretching and cryotherapy, 3 times a week on alternate days for 6 weeks. Spasticity and hand function were assessed pretreatment and post treatment using the Modified Ashworth Scale (MAS) and Manual Ability Classification System (MACS). We tried to find out the additional effect of NMES on spastic CP patients.

Physiotherapy Treatment For Spasticity
5.Patientlimb undergone any surgery for upper limb
Thirty patients of CP who fulfill the inclusion criteria were included in this study. Total numbers of patients were equally divided into two groups (A & B). Each group contained 15 patients. All participants were evaluated by modified ashworth scale for wrist flexor spasticity and manual ability classification system for hand
30 subjects were selected by means of convenience sampling based on inclusion and exclusion criteria. All the parents received a written explanation of the trial before entry into the study and then gave signed consent to participate their children in the study. The patients were randomly allocated into 2 groups.
EXCLUSION CRITERIA
Cold application has been used for some time to reduce spasticity clinically. Decrease in resistance to passive stretch lasts from a few minutes up to 24 hours. Cold anesthesia of peripheral sensory end-organs changes the balance of facilitatory-inhibitory influences playing on the anterior horn cell in favor of inhibition. Unmasking of spasticity permits strengthening of voluntary mechanisms normally snowed under by undesired reflexes.10

Scale measure spasticity and is applied manually to determine the resistance of muscle to passive stretching. This scale has been shown too valid and reliable. 16 Manual Ability Classification system describes how children with cerebral palsy (CP) use their hands to handle objects in daily activities. MACS describe five levels. The levels are based on the children’s self-initiated ability to handle objects and their need for assistance or adaptation to perform manual activities in everyday life. The objects referred to are those that are relevant and age-appropriate for the children, used when they perform tasks such as eating, dressing, playing, drawing or writing.17 MACS has shown to be valid and reliable.18 All patients were assessed by modified ashworth scale and manual ability classification system before and after giving intervention.

Neuromuscular electrical stimulation has gained support since its inception as a treatment for cerebral palsy in the 1970s. With neuromuscular electrical stimulation, electrical stimulation of sufficient intensity generally to produce visible muscle contraction is applied at the muscle motor point. Electrical stimulation is thought to improve strength, reduce spasticity of the antagonist muscle, reduce co-contraction, and create soft-tissue changes permitting increased range of motion. 13 There are few studies that report the effectiveness of NMES and cryotherapy on reduction of spasticity & improvement of hand function in patients with spastic cerebral palsy and found that both the modalities used are effective and none of the two modalities is superior to other.14 Therefore, aim of this study is to determine the effectiveness of Neuromuscular electrical stimulation combined with Cryotherapy on spasticity and hand function in patients with spastic Cerebral Palsy.
INCLUSION CRITERIA
In present study, hand function is measured using the Manual Ability Classification System (MACS) instead of Zancolli system 14 because a review of classification systems of upper limb function & deformity in cerebral palsy supports the use of MACS to classify upper limb function and Zancolli system is recommended to classify thumb, hand &wrist deformity.15

After cryotherapy, subjects received electrical stimulation to the dorsum of the forearm. The electrical stimulation was consist of a dual channel devise with current outcome between 0 and 100 MA , pulse width of 200 microseconds and the pulse set between 30 and 40 Hz to produce tolerable muscle contraction. The electrical stimulation was applied for duration of 30minutes, 3 times in a week on alternate days for a period of 6 uninterrupted weeks.

The subject was placed in sitting position. The entire forearm from elbow to the fingers was carefully and decently exposed. The area was cleaned with cotton wool and with methylated spirit. The upper limb of the subject was positioned on a pillow on the plinth with the shoulder in mild abduction. The forearm was also positioned in mid flexion and supination with the fingers and thumb in anatomical position .The ice lollipop was applied to the flexor compartment of the forearm and gently massaged using stroking technique from the proximal to the distal end of the forearm. This was applied continuously for 20 minutes. The sequence of treatment was 3 times a week on alternate days for 6 uninterrupted weeks.
Following the application of passive stretching, the subjects received Cryotherapy as describe for the subjects in group A.
Patients in both the groups were assessed at baseline level for spasticity with modified ashworth scale & hand function with manual ability classification scale prior to the commencement of the treatment sessions. Post-test measurements were taken after 6 weeks after completion of treatment sessions. There were no drop outs in the study. A total of 16 female and 14 male subjects participated in the study.

In this experimental design study, result showed the combined effect of neuromuscular electrical stimulation and cryotherapy on spasticity and hand function in patients with spastic cerebral palsy. The results support the hypothesis that NMES along with cryotherapy produce good results as compared to cryotherapy alone. Cold facilitates alpha-motor neuron activity and decreases gamma motor neuron firing through stimulation of cutaneous afferents. There is also a decrease in the afferent-spindle discharge by direct cooling of the muscle. When nerves are cooled, synaptic transmission are impeded or blocked by altering the transmembrane ionic flow. The possible explanation of the mechanism of relief of spasticity can be that cold anesthesia of peripheral sensory endorgans changes the balance of the sum of facilitatoryinhibitory influences playing on the anterior horn cell in favor of inhibition. Unmasking of spasticity permits strengthening of voluntary mechanisms normally snowed under by undesired reflexes.10
The result obtained from the study data showed that there was significant difference within group A and B in reducing spasticity and improving hand function. Group A showed more significant difference in outcome measures in comparison to group B.

CLINICAL IMPLICATION
Subjective measures used for measuring spasticity and hand function challenges the results obtained. No follow up was taken to see the long term effects. Dominating hand was only treated in quadriplegics to avoid collecting paired data.

The results of this study are supported by previous studies which tell that the neuromuscular electrical stimulation is helpful in increasing muscle strength by increasing cross sectional area of the muscle & by increasing recruitment of Type 2 muscle fibers.12 With NMES, unused muscles can be stimulated when needed and the sensory input from NMES can give added sensory awareness of what is happening in the hand to allow motor learning to occur and to permit motor control.20 Neuromuscular electrical stimulation, when applied to the peripheral muscles has a direct effect on the cerebral cortex.21 In group A as we have given cryotherapy first and after that NMES, combined effect of both the modalities leads to significant improvement in experimental group.
Above Table showing mean value of pre MAS and post MAS & pre MACS and post MACS of group B. After analysis, p value is <0.05 which is statistically significant.
Result of this study showed that improvement is more significant in subjects of group A treated with cryotherapy followed by neuromuscular electrical stimulation when compared with subjects of group B treated with cryotherapy alone (table 5). This showed that additional improvement in group A is because of neuromuscular electrical stimulation. First cryotherapy has reduced spasticity in wrist flexors and then NMES applied to wrist extensors has further reduced spasticity in wrist flexors via reciprocal inhibition and increased strength in wrist extensors. Few studies have been done on neuromuscular electrical stimulation and cryotherapy in isolation which shows their effectiveness but the result obtained from this study is novel that proves the combined efficacy of neuromuscular electrical stimulation and cryotherapy on spasticity. Neuromuscular electrical stimulation is a non-invasive therapy and offers a better clinical outcome.
The results of the present study enlighten the use of combination therapy approach (NMES+Cryotherapy) as an more effective approach than the either intervention alone in the clinical settings for the management of spasticity and hand function in patients with spastic cerebral palsy.

Phonophoresis in Continuous Mode Ultrasound has Significant effect in the Reliving Pain in Upper Trapezius Tender Point
Conclusion: continous mode of ultrasound is better for immediate pain relive as compared to pulsed mode when diclofenac sodium is used as the coupling medium.
US is a modality which involves the generation of high frequency sound waves, and their transmission through the skin to the structures desired to be affected. US generators used clinically are limited by government
Purpose: The aim of this study was to find the significance of continous mode on the immediate effect on pain threshold and range of motion which follows a single treatment of tender points in the upper trapezius muscle among using diclofenac sodium as coupling medium.
Sodium Diclofenac was chosen for the experiment for being a well-known and widely used nonsteroidal anti-inflammatory drug whose analgesic effects manifest quickly after administration.8 Evidence from clinical and pharmacological studies imply that Diclofenac exerts its actions by inhibiting cycloxygenase
Tender point is defined as the places on muscles that when touched with enough pressure, elicits a feeling of sensitivity in the location of point. Pain does not refer anywhere else in the body; pain is confined to tender point itself. They are usually no bigger than 1 cm
INTRODUCTION
The mechanism by which ultrasound enhances the transdermal penetration of substances is not entirely clear. One could think of the vasodilation observed on macroscopic examination, but this would certainly not be enough on its own, since it does not imply any change of the waterproof keratin layer of the skin, which should necessarily be altered.8

Instruments and Tool used
The full-circle goniometer, or universal goniometer (UG), is a versatile device for recording measurements of peripheral joint ROM in healthy subjects and in patients. Based on a clinical study of 60 patients with orthopaedic disorders in a physical therapy outpatient department, conclusion was drawn that AROM measurements on the cervical spine made by the same physical therapist have good to high reliability, regardless of whether the therapist used the CROM device or the UG. Repeated measurements with the UG had poor to fair between tester reliability.15

METHODOLOGY
Method of selecting & assigning subjects to groups
VAS is usually a horizontal line, 100mm in length, anchored by word descriptors at each end. The patient marks the line the point they feel which represents their perception of their current state. The VAS score is determined by measuring inn millimetres from left hand end of the line to the point that the patient marks.9Reliability of the VAS for acute pain measurement as assessed by the ICC appears to be high. Ninety percent of the pain ratings were reproducible within 9 mm. These data suggest that the VAS is sufficiently reliable to be used to assess acute pain.10
Independent variables- Ultrasonic Therapy

RESULT
A paired sample t test reveal a statistically reliable difference between the mean number of VAS pre and post in continous mode (M= 6.7333, s =1.03280) and (M= 3.9333, s =1.48645) that the t(14)=12.582, P(á)= .000 at two tail test.
An independent-samples t-test was conducted to compare VAS post treatment in pulsed mode and continous mode. There was a significant difference in the scores for pulsed (M=4.4, SD=1.5) and continous (M=3.93, SD=1.48) conditions; t(28)=0.855, p = 0.400. the result suggest that VAS decreases more in continous mode than in pulsed mode.
An independent-samples t-test was conducted to compare ROM post treatment in pulsed mode and continous mode. There was a significant difference in the scores for pulsed (M=33.73, SD=9.51) and continous (M=37.06, SD=4.19) conditions; t(28)=-1.24, p=0.225. The result suggest that ROM increases more in continous mode.
A paired sample t test reveal a statistically reliable difference between the mean number of ROM pre and ROM post in continous mode (M=27.0000, s=5.29150) and (M= 37.0667, s = 4.19977) that the t(14) = -11.093, P(á)= .000 at two tail test.
A paired samples t test reveal a statistically reliable difference between the mean number of ROM pre and ROM post in pulsed mode (M=-23.7333, s=10.73357) and (M=33.7333, s=9.51290) that the, t(14) = -10.569, P(á) = .000.at two tail test.
Group A were given pulsed ultrasound with diclofenac sodium as coupling medium and Group B were given continuous ultrasound with diclofenac sodium as coupling medium. The ultrasound was given for 5 minutes at 0.8 w/cm2 16. After the treatment pain level and Range of Motion is taken again.

A paired samples t test reveal a statistically reliable difference between the mean number of VAS pre and VAS post in pulsed mode (M=-6.8000, s = 1.32017) and (M 4.4000, s=1.50238) that the, t(14) =8.806, P(á) = .000.at two tail test.
The study concludes that continous mode of ultrasound is better for immediate pain relive as compared to pulsed mode when diclofenac sodium is used as the coupling medium for immediate pain relive in tender point in muscles all over the body.
No volunteers presented any complication of any kind nor did they report any discomfort with the treatment at any time, all of them resuming normal life immediately after the end of treatment Apart from slight redness and a temperature increase on touch, no sign of local irritation was detected by macroscopic inspection of the irradiated areas.8
DISCUSSION
Hence it can be said that continuous mode has more of a thermal effect rather than non-thermal.
Mild heating has the effect of reducing pain and muscle spasm and promoting healing process. Kramer (1987), investigating the increase in conduction velocity in motor and sensory nerves following therapeutic ultrasound, concluded that this was likely to be related to the heating effect of ultrasound.12
According to the study, by using continuous mode of ultrasound there is more pain relive rather than by using pulsedContinuousmode.

mode has been recommended for muscular cellular disorders such as muscle spasm, joint stiffness or pain whereas pulsed mode is preferred for soft tissue repair.12

CONCLUSION
This could be because in pulsed mode the time average intensity is reduced which reduces the amount of energy available to heat the tissues while ensuring that the energy available in each pulse is high enough for mechanical or non-thermal effects rather than the thermal effects to predominate.12
Diclofenac sodium is a very commonly used nonsteroidal anti-inflammatory drug (NSAIDs). It is an analgesic-anti-pyretic-anti-inflammatory drug, similar in efficacy to naproxen. It inhibits PG synthesis and is somewhat COX-2 selective.13
In this study, the clinical efficacy of diclofenac gel as a coupling agent using continuous mode of was compared with pulsed mode.
According to the unpaired t test done between post values of VAS in case of pulsed mode and continous mode the p value is <0.005. The post value of ROM in pulsed mode and continous mode the p value is <0.005.

Attention is one of the aspects of cognitive functioning that has been reported as the basis for other components of cognition.7 Visual attention is a type of selective attention that lays a very important role in balance because balance is maintained mainly by feedback through eyes, ears and vestibular apparatus. In this visual contribution is inevitable and if there is visual inattention, then there will be difficulty in feedback mechanism and this will directly affect the balance and eventually ADLs. Visual impairments commonly encountered by patient with hemiplegia include poor eyesight, diplopia, homonymous hemianopia, damage to visual cortex and retinal damage. 8 In its purest form, unilateral spatial inattention is defined as a condition in which an individual with normal sensory and motor system fails

Background: Stroke is a focal neurological disorder lasting for more than twenty-four hours, giving rise to functional disabilities in speech, vision, balance and ADL. As stroke has been found to impair vision, balance and ADL, this study is done to predict the relationship of visual attention deficits to balance and functional outcomes in persons with subacute stroke. Awareness of such relationship may be of useful assistance to the physiotherapists in planning treatment interventions in persons with subacute stroke.
Stroke is an acute onset of neurological dysfunction due to an abnormality in cerebral circulation with resultant sign and symptoms that correspond to involvement of focal areas of brain.1 Cognitive deficits are common after stroke2,3 and have been linked to poor recovery of ADL (Activities of Daily Living) abilities and rehabilitation outcome.4,5 For many people, these impairments are the major obstacles preventing their return to independence and quality of life.6

ABSTRACT
Materials and Methods: 50 subjects with subacute stroke were selected for the study. All the patients were assessed on the basis of Star Cancellation Test (SCT), Berg Balance Scale (BBS) and Barthel Index (BI) for visual attention, balance and functional outcomes respectively both at the time of discharge from the hospital and also after 6 months post-stroke. At the end of the study, visual attention scores were correlated (using Pearson product correlation "r" value) with the balance scores and functional outcome scores obtained at the time of discharge from the hospital and 6 months post-stroke.
Objective: To predict and estimate strength of the relationship of visual attention deficit to balance and functional outcomes in persons with subacute stroke.

to orient toward, respond to, or report stimuli on the side contralateral to the cerebral lesion.9 Attention is also a key component in learning new motor skills, particularly in the early stages of learning.10 This clearly portraits that attentional component plays a very important role in motor learning and also depicts importance of attention in rehabilitation of stroke patients especially in Motor Relearning Programme which is the latest approach in physiotherapy rehabilitation.Instroke,
physical impairments include motor, sensory, balance, urinary impairment, speech disorder, perceptual problems, etc. Balance has been defined as the ability to maintain upright posture.11,12 In stroke, one’s ability to balance may be impaired because of deficits of strength, range of movements, proprioception, vision, vestibular function and endurance.13 Studies have showed that balance and perceptual disturbance are found as risk factors for falls in stroke patients.14
ADL are the activities necessary for daily self care, personal maintenance and independent community living such as feeding, bathing, dressing, hygiene, and physical mobility.15 Studies have reported decline in cognition, mobility and functional daily activity after stroke.16 Also the presence of visual field deficit is being reported as a significant prognostic sign, predicting both a higher death rate following stroke and poor performance in ADLs, even following rehabilitation.17,18 Further, attention deficits being common among hospitalized people with stroke, a study describing association between distractibility, auditory selective attention, balance and function impairments shown that those who scored well on the auditory selective test had better balance scores at the final assessment than those with auditory selective attention deficits or distractibility.19Howeverthere
are no clear cut studies that show that whether visual attention deficits correlate with balance, and eventually functional outcomes in subacute stroke patients. Keeping in view the above point, this study is set out to predict the relationship of visual attention deficits to balance and functional outcome in patients with subacute stroke. The aims and objectives of the study were 1.To find out the relationship between visual attention deficits and balance at the time of discharge and after 6 months post-stroke.

As shown in table 4, there is strong positive and highly significant (p<0.01) correlation between SCT scores (at the time of discharge) and BBS scores (6 months post stroke) and also between SCT scores (at the time of discharge) and BI scores (6 months post stroke).
There was significant correlation between the SCT scores at the time of discharge from the hospital with the BBS score and BI score after 6 months post-stroke. Thus, the present study not only finds the relationship between visual attention, balance and functional outcome but it also predicts the balance and functional outcome after 6 months with the visual attention score at discharge. However, present study showed that visual attention deficits affect the balance and functional outcome significantly but visual attention deficit is not the only factor that can affect the balance

and functional outcome. The assessment of such attention deficits post-stroke may be a useful tool in predicting functional recovery and response to rehabilitation. Awareness of possible deficits of attention may be of assistance to physiotherapists in planning interventions with patients recovering from stroke.
•The study only included visual attention among the various types of attention.
•Only old aged i.e. above 50 years patients with subacute stroke were assessed to find the prediction, young age stroke patients were not at all assessed.
CONCLUSION
ACKNOWLEDGMENTS
We are thankful to all our subjects who participated with full cooperation and showed voluntary interest
•Same study can be done in subacute stroke patients without ongoing physiotherapy.
Stroke is a focal neurological disorder lasting for more than 24 hours, giving rise to functional disabilities in speech, vision, balance and ADL. Hence, in our study we have tried to predict the relationship between visual attention deficits, balance and functional outcomes in persons with subacute stroke. Results from our study indicates that attention deficits were present among the persons with subacute stroke, Sinclair R (1995) also reported similar findings using some of the same subtests among subacute stroke patients.19 Moreover, the visual attention deficits have a significant influence on the balance both at the time of discharge from the hospital and also after 6 months post-stroke. Sebstina and Vyas (2001)21 also concluded that cognitive and perceptual deficits following stroke influences sitting and standing balance among patients. Visual attention has directly proportional relation with balance. However, findings of Stapleton and colleagues (2001) suggested a weak or no relationship between attention deficits and balance control, but their sample size being too small (n=13) the results can be doubted for being statistically significancant.22
Scope of further studies
Star Cancelation test Berg Balance Scale .944.000HS (Time of Discharge)(After 6 (AfterBarthelmonths)Index6months) .970.000HS
Limitations of the study
•BBS does not include gait items so some other scale can be used to assess the dynamic balance of subjects with stroke.
Visual attention deficits are an important factor responsible for predicting balance and functional outcomes in persons with subacute stroke. There is significant one to one relationship between visual attention deficit to balance and functional recovery in persons with subacute stroke.

Ill treatment or inadequate splinting and rehabilitation after burn injuries inevitably result in debilitating post burn contractures that impair various functional abilities of the involved limb. Among these, hamstring post burn contracture remain a frequent problem due to difficulties of knee extension against the contractile evolution of the scar 4.
Results: The one way analysis of variance was used to compare knee extension range of motion which revealed that both treatment group (ultrasound and cold application) had significant (P< 0.05) gains in knee extension ROM after 2 and 4 weeks post stretching exercises.

Contractures are defined as an inability to perform full range of motion of a joint.1 They result from a combination of possible factors- limb positioning, duration of immobilization and muscle, soft tissue, and bony pathology. Individuals with burn injuries are at risk for developing contractures. Patients with burns often are immobilized, both globally, as a result of critical illness in the severely burned, and focally, as a result of the burn itself because of pain, splinting, and positioning. Burns, by definition, damage the skin and also may involve damage to the underlying soft tissue, muscle, and bone. All of these factors contribute to contracture formation in burn injury.

The effects of Therapeutic Application of Heat or Cold Followed by Static Stretch on Hamstring Flexibility Post Burn Contracture
INTRODUCTION
medical problems and functional deficits. Contractures interfere with skin and graft healing. Functionally, contractures of the lower extremities interfere with transfers, seating, and ambulation. Contractures of the upper extremities may affect activities of daily living, such as grooming, dressing, eating, and bathing, as well as fine motor tasks.2,3
Historically, clinicians have prescribed different static stretching techniques as a means of increasing flexibility 5. Research has shown static stretch to be effective in increasing the length of connective tissue6 Warren et al explored the effects of stretching on rat tail tendon 6.They found that low-load, long duration

ABSTRACT

Conclusion: The results of this study suggest that either deep hot or cold application in addition to stretching exercise is more effective than static stretching alone to improve a hamstring muscle.
stretching of rat tail tendon was more effective in increasing rat tail tendon length than high load, short duration stretching6. Therapists often use deep heating modalities to increase tissue extensibility to allow for increased efficacy of stretching techniques. Wessling et a1 found that static stretch combined with ultrasound increased the extensibility of triceps surae muscle (measured by changes in dorsiflexion) more than static stretch alone 7. Laboratory studies also indicate that passive warming of the musculotendinous unit increases its extensibility 8.9. Noonan et al and Strickler et al interpreted their research as evidence that passive warming may decrease the possibility of strain injury secondary to extensibility changes 8.9
Patients treated from burn injuries at El-Hussein teaching hospital were randomly selected for participation in this study. This study eligibility required that patients be more than 18 years of age; 3 to 8 months after the occurrence of the burn injury; had unilateral scars across popliteal fossa of the knee and the percentage of burn did not exceed 20%, and had no history of other lower extremity pathology.
Inclusion assessment to participate in the study, subjects must have exhibited unilateral tight hamstring muscles. Operationally defined as having greater than 30 degrees loss of knee extension . In addition, subjects who were not involved in any exercise activity at the start of the study had to agree to avoid lower extremity exercises and activities other than those prescribed by the research protocol. During the 8 weeks of training 20 male subjects, with age range from 18 to 32 years, met the established criteria and completed the study.
Subjects material and Subjectsmethod
INSTRUMENTATION
Measurement tools
Measurement of knee extension ROM was made with the subject lying supine with the opposite lower extremity extended and the lower extremity being measured positioned at 90 degrees of hip flexion. The greater trochanter and lateral epicondyle of the femur and the lateral malleolus were palpated and served as landmarks during measurement. We attempted to maintain hip flexion at 90 degrees while the tibia was moved into the terminal position of knee extension, which was defined as the point at which the subject reported feeling of discomfort. Zero degree was considered to be 90 degrees of knee flexion. The goniometric value was recorded. The measurement of knee extension ROM was considered to be an indirect measure of hamstring muscle flexibility, with hamstring muscle tightness being the purported cause of a lack of knee extension ROM. All subjects were measured on the same day and at the same time, before they had stretching for that day. Measurements were taken before
Treatment tools
A sonopulse 434 ultrasound unit was used to administer the deep heat as warming up prior to stretching, on the other hand, Enraf nonius chilling unit C5 was used to deliver cold at temperature average from -12°C to - 6°C prior to stretch.
The basis for using cold in combination with stretching, like heat, is pain reduction and decreased muscle guarding. Cold may relieve pain by acting as a counterirritant10Thepurpose of our study was to determine if the application of a superficial heating or cooling modality, followed by a 1-minute static stretch to the hamstring muscle, increases the efficacy of the hamstring stretch alone.

contracture. Patients assigned to group 1 (n=10 patients, age=23.80 years, and range=60.2) served as treatment group 1 and received deep heat in addition to static stretch for 1 minute. Patients assigned to group 2 (n=10 patients, age=24.30 years, and range=60.2) served as treatment group 2 and received cold in addition to static stretch for 1 minute. Patients assigned to group 3 (n=10 patients, age=24.30 years, and range=60.2) served as control group 3 and received stretch only for 1 minute.
Group assignment
A double-arm (30.5 cm) clear plastic goniometer was used to measure knee extension ROM. Prior to data collection; we performed a pilot study to establish intratester reliability of measurements of knee extension ROM. A test-retest design was used on 10 subjects of similar hamstring contracture, with measurements taken week a part. Reliability was determined using an intraclass correlation coefficient. An ICC of 0.96 was considered appropriate for continuing the study.
Experimental procedure Measurement protocol
To ensure equal distribution of hamstring muscle contracture, the patients were stratified into three groups based on their degree of hamstring muscle
RESULTS
The descriptive characteristics of the subjects in both treatment groups and control group are shown in table (1) There was no statistical difference between the two treatment groups and control group regarding the age, depth of burn, percentage of burn and the duration post burn.

Treatment protocol
Ultrasound treatments were performed using an sonopulse 434 ultrasound unit at a frequency of 1 MHz with an intensity of 1.5 W/cm2. A water based gel, maintained at room temperature, was used as a conducting medium. A template was placed over the musculotendinous junction of the hamstring muscle group to ensure that the treatment area remained at four times the effective radiating area of the transducer head. The principle investigator performed all treatments using the same ultrasound unit which had been recently calibrated. Each US treatment lasted seven minutes. If subjects complained of intense heat or any abnormal sensations, treatment was discontinued.
The equivalence of treatment groups regarding the amount of knee flexion contractures prior to the study was checked by conducting one way analysis of variance on knee range of motion. Inferential analysis of the data obtained in this study was done via 2 X 3 analysis of variance experimental design for treatmentsby-treatments by subjects. For all statistical tests and all follow-up tests, the 0.05 level of probability was used.
DISCUSSION
Our study was designed to obtain a more thorough understanding of stretching protocols for increasing ROM and how the use of therapeutic physical agents can affect these protocols in the clinical setting. According to the data, in a treatment lasting 4 weeks or less, cold packs, or ultrasound prior to stretching or stretching alone achieved similar results in increasing knee extension ROM.
Cold may reduce muscle guarding by reducing the activity of the muscle spindles. Knuttsson and Mattsson suggest that superficial cooling can cause reduction in gamma motor neuron activity through the stimulation of skin receptors17. On the other hand , Newton found

The results of the current study support the findings of other studies that static stretching is effective in increasing hamstring length11,12.
The results indicated that either deep heating or cold application followed by static stretching for one minute was more effective in increasing knee extension ROM than static stretching alone for one minute after 3 to 8 months post burn contracture. These results goes hand in hand with those of Wessling et al 13, who claimed that a significant increase in ankle dorsiflexion with the use of ultrasound combined with static stretch compared to static stretch alone.
Ultrasound and other deep heating modalities are believed to cause collagen to become more extensible, thus increasing the efficacy of a stretch13,14.Fischer and Solomon suggest that heating of the skin reduces gamma motor neuron excitability 15 . This would decrease the sensitivity of muscle spindles, which may decrease muscle guarding. On the other hand, Brodowicz et al16 observed that ice application during stretching increased hamstring flexibility, whereas heat and static stretching was not effective.

All experimental groups in this study produced increases in the extensibility of the hamstring muscle, resulting in increases in PROM when compared with the control group. The group receiving ultrasound prior to stretching obtained the greatest increases in knee extension PROM over a 4-week period. This study will allow clinicians more options in effectively increasing the extensibility of the hamstring muscles. In addition, the results of this study will permit the clinician the choice of a cost-effective treatment alternative in an era of more stringent reimbursement.

ABSTRACT
Conclusion: Pulsed electromagnetic therapy, in conjunction with conventional therapy program, was effective in improving functional recovery in children with Erb's palsy.
Design: Randomized controlled trial.
Pulsed Electromagnetic Therapy Improves Functional Recovery in Children with Erb's Palsy
Children with BPL are at risk for developing complications such as progressive contractures, bony deformities, scoliosis and posterior shoulder dislocation 5. Most infantile injuries to the brachial plexus predominantly involve the upper trunk (C5,6); the classic Erb’s palsy which results from excessive lateral traction on the head away from the shoulder. The infant with upper plexus palsy (C5, 6, 7) keeps the arm adducted and internally rotated with the elbow extended, forearm pronated, wrist flexed and the hand in a fist. In the first hours of life, the hand also may appear flaccid but strength soon returns 5. Papazian and associates 6 reported that unfavorable functional outcome is related more often to aberrant reinnervation than to lack of reinnervation. Aberrant reinnervation is especially common in brachial plexus lesions secondary to the close proximity of the nerves involved.

Methods: Children were divided randomly into two equal groups, control and experimental. Both groups received a physiotherapy training program; in addition, the study group received PEMFT for 30 min. Treatment regimen was once a day, three times/ week for three months. Measurements of the affected upper extremity (length, girth and width, muscle strength and range of motion) were carried out before and after treatment.
INTRODUCTION
Obstetric brachial plexus lesions (OBPLs) are typically caused by traction to the brachial plexus during labor. The incidence of OBPL is about 2 per 1000 births. Most commonly, the C5 and C6 spinal nerves are affected. The prognosis is generally considered to be good, but the percentage of children who have residual deficits may be as high as 20% to 30%1. The incidence ranges from 0.38 to 3 per 1000 live births in industrialized countries. The difference in incidence may depend on the type of obstetric care and the average birth weight of infants in different geographic regions .Improvements in obstetric technique have lowered the prevalence of obstetrical brachial plexus palsy to the range of 0.19-2.5 per 1000 2. The incidence of permanent impairment is 3-25% and the rate of recovery in the first few weeks is a good indicator of final outcome. Complete recovery is unlikely if no improvement is noted in the first two weeks of life 3.The neonatal injury is clinically classified according to the nerve roots involved. Injuries affecting the upper plexus(C5,C7
Subjects: Thirty patients were included (16 males and 14 females) with age ranged from six to twelve months (mean=7.3±1.1).

Data was presented as mean and standard deviation. Paired t-test was used to analyze the data within each group and unpaired t- test was used to analyze the data between study and groups. The p-value was <0.05.
birth, all participants were having free passive ROM in all joints of the affected upper extremity, active movement score grades ranged from two to four. Exclusion Criteria: History of malignancy, inflammatory diseases or any surgical intervention of the affected upper extremity. Informed consent was obtained for all patients separately and signed by the parents of the patients.
The purpose of the study was to evaluate the effectiveness of PEMF in improving functional recovery of the affected upper extremity in patients with Erb’s palsy.
All children participated in one measurement session before and after the suggested period of treatment in warm environment with the affected arm undressed. The affected arm length, forearm and hand length (cm), arm and forearm girth (cm) were measured and recorded by means of tape measure. Range of motion of shoulder abduction and external rotation, elbow flexion and wrist extension was also evaluated by using goniometer. The paediatric physiotherapist facilitated maximal shoulder abduction and external rotation, elbow flexion, forearm supination and wrist extension of the affected upper extremity through play, and quantified them on the active movement scale and joint movement grading scale.
Thirty patients were included (sixteen boys and fourteen girls) suffering from Erb’s palsy. Regarding the side of injury, there were 19 patients (57%) with right side and 11patients (33%) with left side. They were selected from different pediatrics out-patient clinics. The children were divided into two equal groups (control and study groups). Inclusion Criteria: All patients were between six to twelve months in age, asymmetry Erb’s palsy was the sole reason for referral to the physical therapy out-patient clinic, onset of the injury was from

The application of pulsed electro-magnetic field therapy (PEMFT) for treating specific medical problems such as arthritis, chronic pain syndromes, wound healing, insomnia, headache and others has steadily increased during the last decade7. Results from basic science research demonstrated certain biological effects of PEMFT that provide a rationale for investigating more potential clinical benefits. Human and animal organisms consist of a large number of cells which function electrically .These cells have rest potential that is necessary for normal cellular metabolism. Diseased or damaged cells have an altered rest potential. If the ions move into an area of pulsating magnetic fields, they will be influenced by the rhythm of the pulsation. The rest potential of the cell is proportional to the ion exchange occurring at the cell membrane. The ion exchange is also responsible for the oxygen utilization of the cell 8. Pulsating magnetic fields can dramatically influence the ion exchange at the cellular level and thereby greatly improve the oxygen utilization of diseased or damaged tissues. The deterioration of the oxygen utilization is known to be a problem in several medical branches, especially delayed healing. There are no contraindications to magnetic therapy except in cases of hemorrhage or where electrical implants are in use. Previous studies indicated that PEMF of proper frequency, intensity and duration provides beneficial effects in a wide variety of cellular processes and mechanisms9. In the field of nervous tissue injuries, previous studies found positive effects of PEMF therapy. Byers et al 10 reported that PEMF stimulation enhanced early regeneration of the transected facial nerve in rats.
The control group was assigned for conventional physical therapy exercise program consisting of positioning, facilitatory stimuli, functional strengthening exercises, passive range of motion exercises, stretching exercises, scapular mobilization, manipulative exercises and splinting. The study group was assigned for PEMF followed by the previously mentioned physical therapy program. During PEMF application, the patient was placed in the supine position and the affected arm was comfortably placed inside a closed pediatrics circuit coil, using PEMF device (EL0064 MAGNETO II). The device generated a pure magnetic field output signal that employed direct current with unidirectional biological frequencies 20 Hz and intensity 0.3 mT (0.03 mT=30 Gauss). Induction of treatment took place for 30 minutes. Treatment for both groups continued for three months, three sessions per week, each session lasted about one hour.

different degrees of injury and respond differently to therapeutic interventions. Experience in treating children teaches that children who present at six months of age with no signs of recovery generally are subjected to development of sequelae, including mild scapular winging, inability to fully supinate the forearm, limitation in shoulder abduction and forward flexion. In the current study, there was no need for electrophysiological monitoring or guide as muscle strength can be considered as an indicator for prognosis and recovery. This is supported by Yilmaz and coworkers 11 who compared magnetic resonance imaging (MRI), electrophysiologic studies, and muscle strength scoring in infants with BPP to determine which indicator provided the most accurate prognosis of the outcome at one year. They found that scoring of muscle strength (eg, elbow flexion; wrist, finger, and thumb extension) was the most reliable measure, with 94.8% confidence at 3 months.

Many mechanisms could explain the improvement in children with Erb’s palsy as biological stimulation by PEMF exposures can modify cellular functions in bone and nervous tissue, and evidence is accumulating that the regeneration capacity of the tissue may be affected6. For example, selective changes in levels of calcium , cyclic adenosine monophosphate, the synthesis of collagen and proteoglycans, DNA, and RNAhave been demonstrated in osseous, nervous, and mesenchymal tissue 12,13,15,16,17,18.
CONCLUSION
The results of the present study showed that the main advantages of PEMFT are the enhancement and acceleration of the recovery of injured nerve tissue. Also, it indicates that PEMFT is a low-cost, non-invasive, non thermal method of physical therapy modalities and should be recognized as standard additional treatment for improving the functional recovery in patients with Erb’s palsy.
There have been few reports about the effect of PEMF therapy on muscle strength and functional activities in children with brachial plexus injuries (Erb’s palsy). The results of the present study showed clearly the beneficial effects of PEMFT on improving muscle strength, range of motion and functional activities of the affected upper limb. These findings coincide with that of Zborowski et al 12 who evaluated the effects of a low frequency electromagnetic field on fast axonal transport changes in speeds and densities of retrograde fast organelle transport in the rat sciatic nerve. Preparations were measured in vitro upon exposure to 15 and 50 Hz pulsed magnetic fields with peak intensities of 4.4 and 8.8 mT. They reported that strong effects were observed in myelinated axons. Such effects may eventually be used as part of a neuroprosthesis to noninvasively modify or couple to various parts of the nervous system. These findings also, are supported by Sharrard et al14who concluded that pulsed electromagnetic fields have encouraged healing of fractured bones and benefited re-anastomosis of peripheral nerves after transection.
The invaluable assistance of the paediatric physical therapists in the out patients clinics to the study are much appreciated

ABSTRACT
Method: 30 subjects diagnosed by an orthopedic surgeon as having adhesive capsulitis of shoulder joint and who showed a typical restriction of external rotation and abduction were selected. Subjects were randomly taken, divided into two groups each of 15 subjects. Group A: (n=15):- Treated with PNF stretching. Group B: (n=15):- Treated with self stretching. Analysis was based on ROM and Shoulder Pain and Disability Index (SPADI) sub scores and total scores.

“ADHESIVE CAPSULITIS” is a common but poorly understood syndrome of painful shoulder stiffness.1 It is most common cause of pain & disability in shoulder in general population.2 Frozen shoulder syndrome was first describe by Duply in 1872. He used the term periarthritis scapula-humerale. In 1934 Codman used the term ‘FROZEN SHOULDER’ first time to describe the condition. 1 In 1945, Nevieser termed condition as “ADHESIVE CAPSULITIS” based on surgically

It is more commonly seen in females than males.2Currently
Background: Adhesive capsulitis of shoulder is characterized by insidious and progressive pain and loss of active and passive mobility of glenohumeral joint. In many physical therapy programs for subjects with adhesive capsulitis of shoulder mobilization techniques are an important part of the intervention. The purpose of this study is to compare the efficacy of PNF stretching techniques and Self stretching techniques in subjects with adhesive capsulitis.
Results: The ROM and SPADI percentage across baseline, 2nd week and 4th week follow up showed a significant improvement statistically in their mean scores within Group A and Group B. Statistically significant greater changes in score were found in PNF Stretching (Group A) for ROM and SPADI as compared to Self Stretching (Group B).

Primary adhesive capsulitis affects 2% to 3% of the general population and is the main cause of shoulder pain and dysfunction in individuals aged 40 to 70 years. The etiology and pathology of this syndrome remains enigmatic. The physical therapy is commonly prescribed for this condition. For predominant adhesive capsulitis and associated soft tissue tightness, mobilizations techniques, PNF stretching techniques have been most commonly address in clinical treatment approaches and research studies.

PNF stretching and soft tissue mobilization is the application of specific and progressive forces with the intent of promoting changes in the myofascia, allowing for elongation of shortened structures. PNF stretching combined with soft tissue mobilization and both are used to effect changes in myofascial length. Contract –relax PNF procedures have been shown to be effective in increasing ROM. The immediate effects of PNF stretching and soft tissue mobilization interventions were demonstrated in a another study using healthy subjects, where improvements were made in hip ROM.8
From the above Table 1, 2 & 3 multiple comparison of active external rotation, active abduction and total SPADI scores shows that difference is statistically significant from baseline to 2nd week and 2nd week to 4th week, but the difference from baseline to 2nd week and 2nd week to 4th week is significantly higher in group A than group B

ABSTRACT
Keywords: P.N.F, Active Warm up, AKE, Flexibility,
Group B: 15 male subjects completed an active warm up on treadmill followed by modified hold relax stretching. The pre stretch measurement was taken by Active Knee Extension (AKE) test. After both the interventions the post stretch measurements were taken at following intervals, 0, 6, 12, 18, 24 min, respectively.
Conclusion: Both the methods are equally effective to improve the range of motion. But the improved ranges can be maintained for larger duration when active warm up was implemented prior to Modified hold relax stretching.

52 Indian Journal of Physiotherapy & Occupational Therapy. January-March 2013, Vol. 7, No. 1
Design: Pre-test, Post-test comparative study with repeated measures.
Method: 30 male subjects were randomly assigned to two groups; Group A- Modified Hold Relax: On the 15 subjects a one time modified hold-relax stretching was performed.
INTRODUCTION
Objective: The study aimed to find out how long the flexibility lasted after a one time modified hold relax stretching & active warm up and its comparison with modified hold relax technique alone.
Setting: Mata Gujri Fitness center, Kailash colony, New Delhi.
hamstrings strains in the athletic population, hamstrings tightness as shown in some studies have shown that reduced hamstring flexibility is considered to be one of the leading cause/risk factor for patellar tendinopathy and patellofemoral pain etc..3 In the ACSM’s guidelines,a clinical evidence for
Results: A significant improvement in ROM was observed when post stretch measurements were compared to pre test in both groups respectively. However, the flexibility lasted for longer duration that is 12 min in group B when compared to group A that is 6 min.
Flexibility is an essential component for normal biomechanical functioning in sports. The length of the muscle tissue is thought to play an important role in efficacy and effectiveness of human movement. 1 Theoretically, a more flexible muscle-tendon unit should be more compliant to external loads, less stiff, and less likely to be injured.2 In sports even small change in performance can have a drastic effect on the outcome of an event.Besides
relationship between hamstring inflexibility with avulsion fractures of ischial tuberosity ,muscle strain, low back ache and increased sway back or round back posture has been mentioned. 4 Proprioceptive neuromuscular Facilitation (PNF) exercises are designed to promote the neuromuscular response of the proprioceptors.There exists a limited data regarding the lasting effects of increased ROM post stretching. The duration of increased flexibility in the previous research conducted by De pino et al, after one time static stretching was found to be of 3 minutes, further Spernoga et al carried out similar study in which, after one time modified hold relax lasting effects remained for 6 minutes, but this is a very short span of time, till date limited studies have carried out to improve the lasting effects. 5, 6. Hamstring flexibility has been measured by active knee extension test, passive knee

at 0 minutes (immediately) and at 6, 12, 18, and 24 minutes after the final stretch in the group A The group B underwent the same post stretch measurement protocol immediately after performing warm up on a treadmill for 5 minutes followed by stretching. The measurement of the angle of knee joint ROM was recorded .The deficit (tightness) was calculated by subtracting the available range from the full range.5
Pre test post test design with comparison in the two groups with repeated measures.
Thus present study aimed to extract the information that for how much duration the flexibility would be retained after a warm up and modified hold relax technique. In many clinical situations, patients may be seen by practitioners once or twice a week, or even less commonly in non-acute situations. It is therefore important to examine whether modified hold relax stretching produce either a greater or longer lasting effect on range of motion. The objective of this study was to investigate whether the application of a single session of modified hold relax was more effective, and has longer lasting effect, than a single session of modified hold relax stretching with warm up on the extensibility of the hamstring muscles measured by AKE over 6 different time interval (pre-treatment, immediately, 6, 12, 18 and 24 minutes) using goniometer.
The 30 subjects were randomly allotted to Two groups viz group A- Modified hold relax ,& Group B active warm up and modified hold relax.
STUDY DESIGN
Procedure In prestretch measurements, subjects in both the groups performed a total of 6 AKEs with a 60second rest period between repetitions. The sixth AKE was recorded as the prestretch measurement. For Post stretch Measurement : AKE measurement were taken

METHOD
extension test, the sit and reach test and the assessment of hip flexion. Range following the straight leg raise, however reliability of these methods has not been demonstrated. An active knee extension test is however a reliable method for assessment of hamstrings.7 Warm up consists of active or passive warming of body tissues in preparation of physical activity. 8. There is a wide spread belief that a warm up contributes to improved athletic performance.9 Active warm up involves exercise and is likely to induce greater metabolic and cardiovascular changes than passive warm up.10 To our knowledge no specifically warm up oriented studies with regards to modified P.N.F hold relax technique has been carried out to assess the lasting effects after a specific warm up intensity.
Instrumentation Goniometer, Treadmill (Sports Art Fitness), Stop watch.
For each stretch, the investigator passively stretched the hamstrings until the subject first reported a mild stretch sensation and that position was held for 7 seconds. Next, the subjects were asked to perform maximal isometric contractions of the hamstrings for 7 seconds by attempting to push their leg back toward the table against the resistance of the investigator.5 after the contraction, the subjects were instructed to relax for 5 seconds. The investigator then passively stretched the muscle until a mild stretch sensation was reported. The stretch was held for another 7 seconds. This sequence was repeated 5 times on each subject in these experimental groups.5
Group B- Active Warm up and Modified hold Relax Maximal heart rate was calculated by the formula, M.H.R=220-age.Thedifference
between maximum heart rate and resting heart rate is known as heart rate reserve(HRR). Target heart rate = (HRR fraction) (HR max –HR at rest) +HR rest .The intensity fraction of HRR was selected at 60 %. As per the ACSM’s position stand this percentage represents lower intensity values enough to produce the adequate training effects for cardio respiratory fitness of warm up. 11.

The alpha level of pd” 0.05 was accepted as significant for all analyses. Mean values and their standard deviations were calculated for each variable. The one way ANOVA (analysis of variance) was carried for both the groups to compare the ROM within each groups to pre stretch measurements. A t-test was performed to compare ROM within both the groups. The data was further analyzed by Dunnet’s post hoc test.

The ONE way analysis of variance revealed a significant difference between pretest and post test ROM measurements within groups respectively. However a Dunnet’s post hoc analysis indicated that a significant (p<0.05) increase in hamstring flexibility was maintained in modified hold relax group for 6 min after stretching protocol. Similarly increase in hamstring flexibility was maintained in Active warm up & Modified hold relax group for upto 12 min.

The present study revealed that there was no statically significant difference in ROM gains in both the groups. This shows that there is no extra improvement/change in ROM when the modified hold relax stretching was performed after the warm up. This findings are similar to that of Cornelius et al in which they concluded that effective increases in tissue length were not affected by warm up when a modified hold relax technique was used.27

Previous researchers have attempted to explain improvements in flexibility with viscoelastic properties, overcoming the stretch reflex, or increasing the stretch tolerance 23. Musculotendinous units function in a viscoelastic manner, and, therefore, have the properties of creep and stress relaxation. Creep is characterized by the lengthening of muscle tissue due to an applied fixed load. Stress relaxation is characterized by the decrease in force over time necessary to hold a tissue at a particular length.

The musculotendinous unit deforms or lengthens as it is being stretched and goes through elastic and then plastic deformation before completely rupturing. Our results suggest that a single session of hold-relax stretching does not deform tissues enough to produce a permanent change (i.e., a plastic deformation in the musculotendinous unit). Therefore, the temporary improvement in hamstring flexibility may be attributed to changes in the elastic region caused by a single session of hold-relax stretching.5

Neural properties
The proposed neural inhibition reduces reflex activity, which then promotes greater relaxation and decreases resistance to stretch, and hence greater range of movement 13 moreover, other research has found PNF techniques to promote greater relaxation.14
Various studies have been conducted in the past to assess the effects of various interventions on improving hamstrings flexibility. However limited studies have been performed which evaluated the lasting effects.5,6,12 These recently conducted studies on checking acute effects of stretching revealed that the flexibility would last for 3 min after static stretching & for upto 6 min after one time modified hold relax stretching. These lasting effecs were present for very less duration. The relatively short time of increased hamstring flexibility may be due to several factors The most prominent are the viscoelastic, thixotropic, and neural properties of the musculotendinous unit.
Thixotropy is the property of a tissue to become more liquid after motion and return to a stiffer, gel like state at rest. The thixotropic property of muscle is thought to result from an increase in the number of stable bonds between actin and myosin filaments when the muscle is at rest. Hence, the stiffness of muscle increases. Because we asked our subjects to lie still in between the readings, the thixotropic properties of muscle may have played a part in reducing the time that hamstring flexibility was increased.
A linear relationship exists between the time a muscle remains still and the stiffness of that muscle in response to a stretch, and indeed, flexibility decreased in both groups as time passed .However, with activity, the muscle becomes more fluid-like because the stable bonds are broken or are prevented from forming. Based on thixotropic properties, we would expect the temporary increase in flexibility to bemaintained during periods of activity and to decrease during periods of inactivity.
In the present study, flexibility lasted for larger duration i.e. 12 minutes in Group B (modified hold relax and active warm up) which may be due to the various factors. These findings are similar to that of various studies conducted by Cornelius which stated that raised tissue temperature, coupled with stretch, would result
Possible effects of warm up due to elevated temperatures are decreased resistance of muscles and joints, Greater release of oxygen from haemoglobin and myoglobin,Speeding of metabolic reactions, Increased, nerve conduction rate, Increased thermoregulatory strain.These

An increase in intramuscular tissue temperature has a beneficial effect on ability of collagen and the myotendinous junction to deform. The effect of temperature must also be considered in relation to the innervations of the muscle tendon unit. There are reports in the literature that sensitivity of GTO to sustained stretch is increased with increase in temperature and that the GTOs sensitivity to tension is inversely correlated with the mechanical stiffness of the musculotendinous structure in which it lies.

INTRODUCTION
1)Dynamicare:
term referring to mild shortening of a healthy musculotendineous unit. In the human body some muscle or a muscle group gets tightness due to lack of proper exercise.2 The plantarflexor muscles play an important role in the gait cycle
Objective: To compare the effectiveness of superficial heat and Deep heat in combination with static stretching in improving the plantar flexors flexibility in females wearing high heeled footwears.
Background: Lower extremity overuse injuries commonly occurs due to decreased flexibility of plantar flexor muscles in females wearing high heeled foot wears. Plantar flexors shortening are treated by various physiotherapeutic techniques. Superficial heat (moist heat) and Deep heat (ultra sound) along with static stretching are treatment techniques used in physiotherapy.
Interpretation & Conclusion: There was significant difference between the two groups. In conclusion both the treatment programs are highly significant and effective in improving the ankle joint ROM, but ultrasound with deep heating property was found to be more superior as compared to moist heat pack with superficial heating property in improving plantar flexors flexibility in females wearing high heel foot wears.
Method: The study included a sample of 40 individuals those who were wearing high heel > 2 inch. Out of that 20 individuals were in superficial heating group (group A) where moist heat was administered for 15 minutes to Achilles tendon, and remaining 20 individuals were in deep heating group (group B) where continuous ultrasound with frequency of 1 MHz at an intensity of 1.5 W/Cm2 was administered for 7 minutes to the Achilles tendon. Both the groups received 30 seconds of static stretch with 4 repetitions performed 5 times per week. The duration of entire study was 3 weeks and both the group received 1 session per day. Analysis was based on the Goniometer test score.

Heating modalities used in clinical setup for enhancing flexibility of muscle and promoting relaxation are briefly divided into superficial and deep heating modalities. Ultrasound, SWD and MWD fall in the category of deep heating modalities. David Draper evaluated tissue temperature rise during ultrasound treatment in 20 males and concluded that application of continuous ultrasound with 1MHz frequency and 1.5 W/cm2 intensity at the medial gastronemius muscle for 10 minutes in humans raised the mean temperature to 40.3 °C, which was an increase of 4.9 °C.10 Moist pack, IRR, Wax, etc fall in the category of superficial heating modalities. Funk D found that 20 minute moist heat application produced significantly more hamstring flexibility than 30 seconds of static stretching.11

Many therapeutic maneuvers like different stretching techniques namely static stretching, ballistic stretching, PNF stretching and cyclic stretching are useful to increase ROM by enhancing soft tissue extensibility. Worrell TW demonstrated significant increase in ankle dorsiflexion ROM in 11 female and 8 male subjects who received 20 seconds of calf stretching repeated over 10 sessions followed by 10 close kinetic chain gastronemius/soleus stretching sessions.9

Use of high heeled footwear has become a common trend nowadays. Biomechanical problems which seem to be associated with long term use of such foot wears results in shin pain, ankle sprain and altered gait pattern.6 According to the American Orthopedic Foot and Ankle Society, heel > 2 inches are consider as “high” which creates three to six times more stress on the front of the foot than a shoe with a modest one-inch heel, and can lead to bunions, heel pain, toe deformities, shortened Achilles tendons, and Back Pain. 7 AL DALI Waleed et al. confirmed significant reduction in calf flexibility and ankle dorsiflexion range of motion (ROM) in 80 healthy college female students wearing high heeled shoes.8

Each calculated t-value is compared with t-table value to test two tailed hypothesis at 0.05 level of significance.

Number of clinical methods and techniques are available to improve flexibility, viz. therapeutic application of heat in form of superficial and deep heating modality, different stretching technique, pre exercise warm up, etc. In stretching, static stretching is the simplest, useful and most effective technique. This
study consisted of 40 individuals, who were divided into 2 groups - Group A and Group B. Group A consisted of 20 individuals with mean age of 21.00 ± 1.55 and group B consisted of 20 individuals with mean age of 21.10 ± 1.68. Group A was treated with superficial heat (moist heat pack) along with static stretching and group B with deep heat (ultrasound) along with static stretching for duration of 3 weeks. Ankle dorsiflexion ROM with knee in extension was measured as an outcome measure to evaluate the effect of superficial and deep heating on calf flexibility and thereby on dorsiflexion ROM. After retrieving the values, data was statistically compared using paired and unpaired ‘t’ test for comparison within and between the groups respectively.Theresult
‘t’calculated value in all these cases is statistically significant as it is above the ‘t’ tabulated value; hence both the treatments were effective in improving Ankle dorsiflexion ROM.
DISCUSSION
Both the groups showed improvement in ankle dorsiflexion ROM postintervention. Mean±SD of prepost difference in right ankle dorsiflexion ROM for group A was 2.90±1.37 and for group B was 4.25±0.85 and ‘t’calculated value was -3.73 at n 1+n 2 -2 degree of freedom. Mean±SD of pre-post difference in left ankle dorsiflexion ROM for group A was 3.60±1.04 and for group B was 4.35±0.74 and ‘t’calculated value was2.61 at n1+n2-2 degree of freedom. ‘t’calculated value in all these cases is statistically significant as it is above the ‘t’ tabulated value of 1.96.

The individuals were treated with superficial heat along with stretching and deep heat along with stretching for 3 weeks and were found to be effective in improving the ankle joint ROM in both the groups. Statistically when both the groups were compared, group B individuals showed more improvement as compared to group A. In conclusion both the treatment programs are highly significant and effective in improving the ankle joint ROM, but ultrasound with deep heating property is found to be more superior as compared to moist heat pack with superficial heating property in improving plantar flexors flexibility in females wearing high heel foot wears.

statistically when both groups were compared, Group B showed more plantar flexor flexibility as it showed much greater improvement in dorsiflexion ROM as compared to that in Group A and also the ‘t’ calculated value was higher than ‘t’ tabulated value (1.96). This effect of ultrasound can be attributed to the sufficient increase in tissue temperature brought by it and hence thereby promoting greater relaxation of muscle as compared to superficial heating modalities. These findings are in line with those by David Draper (1993 and 1998).13,14 Moreover findings of Hendricson et al. (1984),15 Wessling et al. (1987)16 and Rather Aijaz et al. (2007)17 also support the fact that ultrasound when combined with static stretching as compared to static stretching alone is more effective in improving soft tissue flexibility. Hence it is more suggestible to use a combination of ultrasound and static stretching to improve soft tissue extensibility.
•The study of same treatment approaches with the inclusion of control group can be done.
•A long term follow up study should be done to check the recurrence rate and to know the long term effects of interventions.

Intervention: The patients were randomly assigned into two equal study groups of 15 (A and B). The assessment were performed pre and post application of static splint for group A and dynamic splint for group B. The duration of splint application was one hour for both groups. All participants were receiving designed program of treatment of hemiplegia after application of splint.
Stroke, is defined as a cerebrovascular accident (CVA), it is the rapidly developing loss of brain functions due to disturbance in the blood supply to the brain. As a result, the affected area of the brain is unable to function, leading to inability to move one or more limbs on one side of the body, inability to understand or formulate speech, complications, and may lead to death.1Spasticity
ABSTRACT
caused by an upper motoneuron syndrome is usually defined as a velocity-dependent increase in muscle resistance against passive lengthening because of a supraspinal disinhibition of both tonic and phasic stretch reflexes. This muscle over activity may result in muscle imbalance and shortening, leading to abnormal postures 4. Pain in the hemiplegic upper limb is also widely reported to be a complication of spasticity.2Production of an effective powerful grip or even to manipulate objects requires the wrist to be held in a functional position of slight extension maintained by activity of the wrist extensors4 .The inability to open the hand when reaching for or releasing an object and limited grip is a common functional problem after stroke.

INTRODUCTION
Splinting is commonly used by both physical and occupational therapists to prevent joint deformities and to reduce muscle hypertonia of hemiplegic upper limbs after stroke.4 Orthoses and splints are commonly used to improve and correct the position, range, quality of movement, and function of a person’s arm or hand 5.
It is proposed that inhibition results from the application of splint can be due to altered sensory input from cutaneous and muscle receptors during the period of splint or cast application. Immobilization, applying gentle continuous stretching of the spastic muscle at submaximal passive range of motion (PROM), is seen to reduce spasticity by altering the threshold response to stretch of the muscle spindle and Golgi tendon organs in the antagonist and agonist muscles. The effects of neutral warmth and circumferential contact are also thought to contribute to modification of spasticity seen following casting.4
Indian Journal of Physiotherapy & Occupational Therapy. January-March 2013, Vol. 7, No. 1 65
It may be due to weakness of the finger extensor muscles, spasticity and stiffness of the finger and wrist flexor muscles. Grip can be limited not only because of an inability to activate finger flexors but also because of weakness of the wrist extensors (extensor carpi radialis longus, extensor carpi ulnaris).3
Influence of different Types of Hand Splints on Flexor Spasticity in Stroke Patients
Outcome measures: (1 The mean of active and passive range of motion for wrist extension using goniometer, and 2) Grip strength by using digital hand dynamometer.
Subject: 29 hemiplegic (stroke) patients (45-65 Y/o) with mild to moderate spasticity of upper limb. The onset of stroke was from 6 month to one year before starting the study.
Objective: The aim of this study is to evaluate the efficacy of each static and dynamic splint on hand flexor spasticity and to compare between their effectiveness on hemiplegic patients.
INSTRUMENTATION
All patients of both groups were evaluated at the beginning and at end of one-hour period of splint application. Patients of G1 were wearing static splint for one hour while, patients of G2 were wearing dynamic splint for one hour .Changes occurring with static splint were then compared with changes occurring with dynamic splint. Because the way in which the splint is fitted to the arm may be important, the fitting was performed by the same trained investigator. All assessments were performed in a quiet room while the patient was sitting with the shoulders relaxed and arms resting comfortably on chair’s arm support.
Hand digital dynamometer was used to measure the grip strength of affected hand. Goniometer was used to measure active and passive range of motion of wrist extension. Two types of splints were used in this study. The static splint made from a low-temperature, nontoxic, biodegradable material produced from a strictly controlled cotton tissue, the splint held the hand in the functional resting position (wrist positioned between at 30 degree extension), thumb in abduction 2 The dynamic splint was costumed made from thermoplastic material and allowed 30 degrees of movement at the wrist and the fingers were free 9
The types of splint designs commonly used are dynamic splint and static splint. The dynamic splints designed to maintain wrist joint alignment with allowing movement at the wrist would improve performance while maintaining activation of the forearm muscles that control the wrist. In addition, the dynamic splints would preserve and perhaps enhance grip and manual dexterity skills7. Otherwise static splints are designed to be rigid for controlled immobilization of the involved joint for improved function8.Inastudy
INTERVENTION
comparing muscle activation patterns during perturbed balance when static and dynamic ankle splints were worn, investigators reported that static splints decreased muscle activation in ankle musculature7. In contrast, dynamic splints allowed activation of ankle muscles while improving balance function. In addition, proximal muscles in the trunk and thighs were more active with the static splints than with the dynamic splints, suggesting increased muscle activation proximal to the joint, which is fixed or immobilized during static splint conditions 6.
Also an overnight splint-wearing regimen with the affected hand in the functional position does not produce clinically beneficial effects in adults with acquired brain impairment 10. For optimal efficacy, therapies aimed to improving function should address both muscle shortening and muscle over activity; measures to relax overactive muscles should be combined with physical treatment to lengthen them9.
Therefore, the goal of the current study is to evaluate and compare between the short term efficacy of
Twenty nine stroke patients (17 women, 12 men) were recruited from outpatient departments in King Fahad Hospital of the University. Subjects were required to meet the following inclusion criteria:(1) post stroke hemiplegia with duration ranged from 6 months to one year before the study; (2) upper-limb mild to moderate spasticity (Modified Ashwarth Scale 1+ to 3 at the wrist), and (3) age between 45 and 65 years . Exclusion criteria were : (1)cognitive impairment, (2) major contracture affecting muscles of the spastic arm at the time recruitment; (3) Joint pathology of the upper limb (eg, previous fractures, articular blocks); (5) Patients under antispastic drug . Informed consent was obtained for all patients separately . Subjects were arranged randomly into two groups; group I (G1) and group II (G2). Group I consisted of 14 patients (9 males and 5 females) and group II consisted of 15 patients (8 males and 7 females).
MATERIALS AND METHOD
Subjects
The biomechanical effects of splinting relate to changes in the length and extensibility of muscle and connective tissue. Application of low-load prolonged stretch to the contracted tissues at the end of their available range allows histological changes to occur in the tissues in response to the position imposed6. It was suggested that the increase in passive ROM seen after removal of casts in hemiplegic and cerebral palsy clients results from the lengthening of connective tissue elements along with addition of sarcomeres to the muscle fiber5

Many studies concluded the effects of dynamic splints on upper limb in hemiplegic patients that they could reduce swelling, improve wrist posture, and reduce wrist and finger flexor spasticity9. Other study recommended that daily use of static splint in poststroke upper limb spasticity over an extended period is associated with reduction of spasticity and pain, and with an increase in wrist PROM8.

Further investigation is necessary to determine efficacy of the different splints over time and in different functional activities to more clearly understand splinting use for spastic hand in hemiplegic patient.
The study findings suggested that spastic hand in hemiplegic patient may experience improvement in PROM , AROM and hand grip strength as a result of static and dynamic splint application , but better results were found when dynamic splint were worn during the same time of application .
Also , the current results counteract with (Turton and Britton 2006)11 that found that application of an intensive 4-week splinting program to prevent contractures in the arm after stroke did not increase the extensibility of the wrist and long finger flexor muscles in adults after stroke, this trial evaluating stretch positioning in the upper limb, reported a loss of 13° of wrist extension range at 8 weeks.

This study was designed to investigate the short term efficacy of dynamic and static splints on hand flexor spasticity in stroke patient and compare between them by changes in degrees of active and passive range of motion and grip strength. The result showed that patient with spastic hand in both groups had demonstrated improvement after application of both types of splints .However; the dynamic splint had significant improvement in wrist AROM, PROM & grip strength compared with static splint.
activation patterns of the upper extremity muscles of ten children with CP were compared during reaching with and without a hand-positioning device. Results suggested more normalized muscle activation with the device application16 .In contrast, another study using static splints that immobilize wrists reported decreased muscle activation, which over time may lead to disuse atrophy in the wrist muscles and overuse of more proximal muscles.17 In contrast, dynamic wrist splints that provide wrist support for more optimal hand function allowed some movement, may not produce this additional strain on proximal muscles19.

ABSTRACT
Subjects: Forty nine patients suffering from distressing post herpetic neuralgia. assigned randomly into 2 groups; interferential group and narrow band ultraviolet B group. Intensity of pain was recorded before and after therapy using numerical rating scale.
current (IFC) is a common electrotherapeutic modality used to treat pain. IFC therapy is the application of alternating mediumfrequency current (4,000 Hz) amplitude modulated at low frequency (0–250 Hz). Despite IFC’s widespread use, information about it is limited. A review of the literature reveals incomplete and controversial documentation regarding the scientific support of IFC in management of post herpetic pain5.
Interferentialeffects4
Keywords: Interferential Current Therapy, Narrow Band Ultraviolet B Radiation, Numerical Rating Scale, Post herpetic neuralgia.
Results: The results of this study showed no significant difference in pain intensity post treatment between both groups in acute and subacute neuralgia as p value > 0.05 while there was significant difference between both groups in established neuralgia as p value< 0.05.
INTRODUCTION
Interferential Current Therapy versus Narrow Band Ultraviolet B Radiation in the Treatment of Post Herpetic IntsarNeuralgiaSalim.Waked
Herpes zoster ( HZ ) infection is caused by a reactivation of the latent varicella zoster virus that causes chicken pox. It appears predominantly in older adults whose immunity for the virus has waned. Postherpetic neuralgia (PHN) is described as sharp, burning, aching, or shooting constantly present in the dermatome that corresponds with the herpes rash1.
Post herpetic neuralgia (PHN) is a common, debilitating complication of herpes zoster that has a major impact on patients’ quality of life. It can cause insomnia, fatigue, depression. Predictors of PHN are greater age, acute pain and rash severity, prodromal pain, the presence of virus in peripheral blood, as well as adverse psychosocial factors3.

mechanism of neuralgia is poorly understood and multiple and complex pathophysiology is postulated requiring poly pharmacy, which itself leads to many side
Objective: To compare the efficacy of interferential current therapy versus narrow band ultraviolet B radiation in the treatment of post herpetic neuralgia.
Pain in HZ evolves in three phases: acute, subacute, and chronic. The acute phase occurs with the onset of the herpetic rash and lasts for less than 30 days, the subacute phase lasts for 1-3 months after the onset of the rash, and the chronic phase, or PHN, lasts for 3 months or longer after the onset of the rash2

Conclusion: The study concluded that interferential current and narrow band ultraviolet B were effective in acute and subacute neuralgia, while only interferential is effective in established neuralgia.
The inflammatory response plays a major role in the pathogenesis of acute zoster pain and PHN. Ultraviolet B radiation (UVB) may affect the course of PHN through its suppressing effect on the inflammatory response in the acute zoster attack, thus decreasing the neuronal damage contributing to PHN 6.
The purpose of this study was to evaluate the efficacy of interferential current therapy versus narrow band ultraviolet B radiation in the treatment of post –herpetic neuralgia.
The treatment of PHN is medically challenging and often frustrating in some situation as the exact
Numeral Rating Scale (NRS) is a common and practical method for assessing pain severity. It is the most widely used pain rating scale in clinical practice. There is evidence, which supports the validity and reliability of the NRS in younger. and older patients. The reliability of the NRS is acceptable and it has a high internal consistency, with a Cronbach á range of 0.86 to 0.88 7
At the time of this study, Human Research Ethics Committee had not been established in the faculty of physical therapy, but the study was approved by the departmental council of physical therapy for surgery and all patients signed an informed consent at the first visit to the physical therapy clinic .
•One electrode, from channel 1, was placed directly beside the origin point where the dermatome exits the spinal cord. The other electrode for channel 1 was placed about 2/3rds of the way down the
combined unit used to introduce interferential current for group 1. This unit introduced a quadripolar IF as well as bipolar mode. The unit was provided with two output channels for interferential currents.
The NRS is an 11-point pain scale, where patients are requested to quantify the intensity of their pain on a scale from zero to 10 (from 0 = no pain to 10 = worst pain imaginable). The NRS scale can also be used visually with both words and numbers along a vertical or horizontal line. Patients are asked to express a number that relates best to their pain intensity8.

PATIENTS AND METHOD
Forty nine patients (24 male, 25 female) with distressing post herpetic neuralgia were recruited from department of dermatology and the study conducted in outpatient department of physical therapy- ElMataria Teaching Hospital after approval of the institutional ethical committee. The history & clinical examination were done for all patients. Subjects who fulfilled the following criteria were eligible for enrollment in the study; (1) age ranged from 50 to 80 years, (2) elapsed time since the beginning of pain less than 6 months. Patients were excluded if they had (1) disseminated zoster, (2) malignancy, (3) diabetes, (4) pregnancy (5) pacemakers (7) Patients were taking immunosuppressive medication. The patients were randomized into two groups of equal number. (1) interferential group and (2) narrow band ultraviolet B ( nbUVB) group. Pain was assessed by numerical rating scale before starting of the treatment and at the end of the therapeutic period for all patients.

Treatment parameters
•The dermatome that was affected by the shingles is the treatment path for electrotherapy. Each channel has one electrode that emits electricity and the other electrode is the ground.
Data were coded and entered to a statistical package of social science (SPSS, version 16). Mann-Whitney U test was used to assess the difference in sex, type of pain, type of neuralgia, affected dermatome as well as the intensity of pain in acute, subacute and established neuralgia between both groups, while wilcoxon test was used to assess the intensity of pain within each group. All p values less than 0.05 were considered to be statistically significant.

The analgesic effect of interferential therapy can be explained in part by Wednesky inhibition of Type C nociceptive fibres, although other mechanisms are certainly involved. ‘Pain gate’ theory, proposed by Malzack and Wall11 remains central to this explanation. Another system that helps to reduce pain is the ‘descending pain suppression mechanism’, which is mediated by the endogenous opiates12.
UVB modifies the T-cell response to persistent VZV particles in nerve fibers, which might be involved in the pathogenesis of PHN. UVB induces a shift from a Th-1 immune response to a Th-2 response in different ways19.Two
As regard to the efficacy of nbUVB; the results of study showed that there was significant reduction of pain intensity in acute and subacute neuralgia however non significant differences in chronic neuralgia. The improvement in acute and subacute neuralgia may be attributed to the anti-inflammatory effect of UVB. UVB may affect the course of PHN through its suppressing effect on the inflammatory response in the acute zoster attack thus decreasing the neuronal damage contributing to PHN17.
Number of previous studies demonstrated the effectiveness of inferential current therapy in order to reduce neuropathic pain. Babu and Murali; 13 and Burchiel;14 analyzed analgesic effects of IFC in chronic and acute neuropathic pain. Natarajan;15 also found positive results of interferential currents in diabetic neuropathy and post-herpetic neuralgia. Nabila; et al;9
of the study showed that there was significant reduction in pain intensity post treatment in IF group in acute, subacute and chronic neuralgia as p value <0.05. This support the efficacy of interferential for minimizing pain and this may be attributed to analgesic effects of interferential therapy.

In a study compared IF with transcutanous electrical nerve stimulation (TENS) Cheing and HuiChan;16confirmed the analgesic effects of IF and TENS in their study and concluded that both TENS and IF increased the heat pain threshold to a similar extent during stimulation. However, the post-stimulation effect of IF lasted longer than that of TENS.
Postherpetic neuralgia is the major chronic complication and is a difficult management problem. The aim of this study was to compare the effects of interferential current therapy versus narrow band ultraviolet B radiation in the treatment of post herpetic neuralgia. A prospective study of forty nine subjects was carried out. Subjects were divided into two groups; IF group that received interferential therapy and nbUVB group that received narrow band UVB sessions. Outcome measures were assessed using numerical rating scale to assess pain intensity pre and post treatment.Theresults
Langerhans cell (LCs) play an important role in PHN as several molecules that sensitize cutaneous nociceptors are released by LCs. And the langerhans may be activated in acute PHN. UVB radiation suppresses antigen presentation of LCs in different ways. It stimulates keratinocytes and mast cells to secrete immunosuppressive cytokines such as IL-10, TNF-á, IL-4, PG-E2, á-MSH or CGRP, which inhibit the antigen-presenting function of LCs. Furthermore, it causes depletion of the LCs in the epidermis 18, which may also explain the improvement induced by UVB in

studies correlate with the results of this study. Jalali et al;20 who reported 58.33 and 83.33% complete pain relief at 1 month and 3 months follow up, respectively. And concluded that UVB phototherapy in the acute stage of zoster rash might reduce the incidence and severity of PHN. Treatment after 3 months does not seem to have a significant beneficial effect. Also ElNabarawy; 10 who used nbUVB for 17 patients with post herpetic neuralgia and the results showed more than 50% improvement was achieved in 6 (35.29%) and 8 (47.06%) patients, at the end of therapy and after 3

best of our knowledge, there is no study comparing the efficacy of interferential therapy versus narrow band ultraviolet B radiation. The results of this study showed no significant difference in pain intensity post treatment between both groups in acute and subacute neuralgia as p value > 0.05 but significant difference in established neuralgia as p value< 0.05. This confirm the efficacy of both interferential and nbUVB for acute and subacute neuralgia, while only interferntial is effective in established neuralgia. The limitations of our study were no control group included and no period of follow-up. Further studies including control group and follow-up are needed to further validate our findings.

ABSTRACT
Background: The athlete's capacity to tolerate pain is one of the most important features of sporting success. Research suggest that a verity of pain suffers can benefit from exercise. Duration of play may increase in pain threshold and pain tolerance in soccer players.
Keywords: Soccer, Pain Threshold, Pain Tolerance Introduction.
Objective: The purpose of this study was to evaluate the effect of pain threshold and pain tolerance on participation in playing soccer.
Design: This was a same subject pre-test post-test trial.
Measurements: A gross pressure device was used to induce pain, and to measure pain threshold and pain tolerance. It consisted of a sphygmomanometer and rubber coated steel cleat. Cleat along with shin guard was placed of the medial surface of the tibia approximately in the middle portion. Pain was induced by inflating the sleeve at 10 mmHg every 10 seconds. The subjects were asked to inform when they first sense pain. The pressure was noted as pain threshold reading. Pressure was further increased till the subject cannot endure it readings were noted as pain tolerance and pressure was released. The readings were taken before, between and after the game.

Such anecdotal evidence has been linked to theory to data which indicate that exercise releases endorphins and that endorphins reduce pain. This proposed linkage has, intern, led to a belief that exercise-induced analgesia is an established phenomenon.2
Willium P. Margan(1984)8 examined the “effective beneficence of vigorous physical activity” and concluded that distraction, release of monoamine as well as endorphins during vigorous physical activities, act synergistically to produce the analgesic effect. Ashley Grossaman and John R. Sutton(1984) 9
Though the growing body of research suggest that a variety of pain sufferer can benefit from exercise, and a greater reliance upon exercise as an effective , healthy and less intrusive pain management alternatives, or adjunctive, to pharmacological analgesics can be laid. However relatively little research has been devoted to examining the effectiveness of exercise on influencing the person’s threshold and tolerance of pain, particularly acute.
It has been reported by Raithel that most pain management programmers prescribe some kind of exercise regimen, some include aerobic exercise, others include resistance exercise, and still others use a combination of aerobic and resistance exercise. Research has been conducted into whether aerobic exercise, such as cycling and running , is associated with an analgesic effect, and has indicated that aerobic exercise at a sufficient intensity (>70% of maximum aerobic capacity) has been associated with increases in pain
The purpose of this study was to evaluate the effect of pain threshold and pain tolerance on participation in playing soccer.

Another study by Conard Droste (1990) 10 on experimental pain threshold and plasma beta –endorphine level dosages does not correlate significantly with pain threshold, though short term, exhaustive physical exercise can evoke transient pain threshold. This exercise induced elevation in pain threshold does not however, appear to be directly related to plasma endorphine level.
PURPOSE
regarding whether or not exercise –induced analgesia is an established phenomenon in humans is equivocal. Haier et al (1981)5 have reported changes in pain threshold following exercise, while others have not. a number of investigators have studied changes in pain threshold using a dental pulp stimulation. Pertovara et al. (1985)6 al investigated changes in dental pain threshold during exercise at different intensities and found that dental pain threshold tends to increase with increasing workload.
Duration of play will increase the pain threshold and pain tolerance in soccer players.
Ronalds Melzack,3 founder of pain gate theory had described pain in his own words in the following ways “ it is not a fixed response to a noxious stimulus ;its perception is modified by past experiences, expectations and even by culture. It has a protective function, warning us that something biologically harmful is happening. But anyone who has suffered prolonged pain would regard it as “Evil”, punishing affection that is harmful in its own right”.
investigated the relationship between the endorphin relies and their role in exercise and found that the endorphin concentration in the blood increases considerably with exercise and play an important role in regulation of ventilation especially at higher intensity exercise , where they appear to inhibitory.
HYPOTHESIS
Subjects
The experiments are typical studies investigating post-exercise analgesia. Their emphasis was not on supporting the casual role of exercise in the analgesic effect, but instead focused on whether the analgesic effect is mediated by release of endorphins. However, while these studies appear to support the analgesic effect of exercise, a causal interpretation is limited by the failure to include a no exercise control group.7
Maria Gurevich (1994)11 and colleagues found that submaximal exercise intensity produces analgesia suggesting the possibility of using moderate exercise in therapeutic intervention. Another study by Mark HA and Kenith Russel (1994) 1 confirmed that resistive aerobic exercises can result in greater pain tolerance.

Winning experiences, social context, coaching style, and the nature of sports all play a role in athlete pain response to meaningful competition and should therefore be considered in athletes who claim to feel no pain following an injury. Exercise induced analgesia is only produced in humans following high level of exercise with a work load of at least 74% aerobic capacity. Each testing session was not aerobically challenging for the participants, and therefore was unlike to lead to significant changes in pain threshold and pain tolerance due to exercise.13

To find out the difference among all the three readings of pain threshold and pain tolerance a repeated measure of ANOVA shows statistically significant difference among all the three readings of both pain threshold (F=17.05,p<0.0001)and pain tolerance (F=19.69, p<0.0001). A bonferonnin post hoc pair wise comparison shows significant difference among three pairs before game vs. between game (pain threshold p=0.02,pain tolerance =0.001) before game vs. after game (pain threshold p<0.0001, pain tolerance p<0.0001) and between game vs. After game (pain threshold p=0.033, pain tolerance p=0.019) which is presented in figure 1.
We believe that the stress component of competition contributes to the pain inhibition associated with physical exertion. In soccer scoring chances are rare, a defensive mistake in soccer, for example, may carry more importance and cause a higher degree of anxiety and a defensive mistake in a basketball game. If a defensive mistake in a basketball game results in a basket for the opposition, many opportunities to make up the deficit are likely to occur. Soccer is a “player’s game,” during a game, athletes are expected to make their own decisions concerning what to do in every situation. Athlete, who participated in soccer or basketball, however experienced similar levels of analgesia prior to game situations. The study provides evidence that the competitive aspects of competition and its physical stressors aroused the SIA mechanism. Much of the existing research on anxiety in sports is too focused on the characteristics of the athlete, while ignoring the characteristics of the environment in which the behaviour took place. Situational variables have been shown to effect emotions elicited by the various competitive environment.12

The results of this study suggest that competition modulate pain threshold and pain tolerance responses to noxious stimuli. Soccer player exhibits higher pain threshold and pain tolerance during and after the game compared to before the game.
Athletes display a rise in pain threshold (analgesia) in response to athletic completion as compared with non competitive testing session. Hormonal levels in soccer players, in game compared to before. Cortsol has been identified as a reliable marker of stress. Both analgesia and elevated cortisol levels measured before games suggest that game situations can be considered as reliable stressors. Many outside factors also contribute to overall physiological status of a player including conditioning activities, practice schedules, academic demands, and physiological stressors, in addition to completion. Such factors consistently affect an athlete’s overall level of stress and confound possible cortisol elevations in anticipation of practice.14
Research suggests that environmental stress is a natural triggers of the inhibition of pain sensation. It follows the athletes experienced both analgesia prior to the game and elevated cortisol level due to the stress of athletic competition. Stress is believed to activate the endogenous opoid system which will cause the observed analgesic response. 15 Cortsol “the stress hormone” is the dominant form of glucocorticiods in humans. ACTH and â-endorphine have roles in the regulation of stress; Both ACTH and â-endorphine have roles in the regulation of stress; ACTH stimulates the adrenal which releases cortisol and â-endorphinebinds to opoid receptors which produce analgesia. Thus, the analgesic findings from the study could be due to the stress elicited from comparative situations, which in turn caused analgesia and subsequently higher pain threshold and pain tolerance. The study supports the

Hand edema following stroke is associated with pain and stiffness, which can lead to a decrease in active motion and disuse. The most widely accepted explanation is due to increase venous congestion related to prolonged dependency and loss of muscle pumping function in the paretic limb6

Subjects: Thirty stroke patients of both sexes (18 females and 12 males).They assigned randomly into 2 study groups each one composed of 15 patients.
Results : The results of this study revealed that application of intermittent pneumatic compression therapy had a significant effect on reducing hand edema in stroke patients than receiving neuromuscular electrical stimulation .While hand function measured by hand grip strength was improved more significantly with receiving neuromuscular electrical stimulation than the group who received intermittent compression therapy.
Conclusion: Application of intermittent pneumatic compression therapy was more effective in reducing hand edema than neuromuscular electrical stimulation while application of neuromuscular electrical stimulation resulting in greater improvement in hand grip strength and hand function.
In hemiplegic patients, swelling of the affected hand is a recognized phenomenon. The mechanism of swelling is uncertain, but it had many predisposing factors as immobility, dependency, impaired venous return and paralysis of the sympathetic control of vasculature.1Edemain paretic hand may be attributed to a combination of dependency and insufficient muscle pump resulted from hemiplegia that will hamper venous return in the affected limb which in turn will increase the capillary filtration resulting in edema which can be the main mechanism of hand edema in that cases.3 4
Objective: the purpose of this study was to evaluate and compare between the effect of application of neuromuscular electrical stimulation and intermittent pneumatic compression on reducing hand edema in stroke patients.
In stroke rehabilitation neuromuscular electrical stimulation (NMES) can be used to modulate neural activity to either regain voluntary muscle contraction
Neuromuscular Electrical Stimulation Versus Intermittent Pneumatic Compression on Hand Edema in Stroke Patients
Method: Group I received intermittent pneumatic compression therapy and group II received neuromuscular electrical stimulation three times per week for twelve weeks. The patients were assessed for hand volume by using the volumetric measurement and by hand held dynamometer to measure hand grip strength before and after the end of treatment period.
INTRODUCTION
ABSTRACT
MATERIAL AND METHOD
The measurements were repeated three times and an average measure was taken for the hand volume and hand grip strength.
The patients in (group II) were given (NMES). The surface electrodes were applied on hand flexor muscle group. This stimulation pattern will be administered to this muscle group for approximately 20 minutes. Electrodes will then be repositioned and applied to the extensor muscle group for approximately 20 minutes. The stimulation was at a frequency of 30 Hz, with a pulse width of 300 ìs. The amplitude of the current was adjusted to the maximal tolerance of the patient, in a range up to 90 micro ampere , with a duty cycle of 5 second on and 5 second off. The total stimuli were 180 cycles during the treatment session. Patients were focusing on the movement induced by (NMES) during the treatment. Treatment lasted for 30 min., 3 days per week for 12 weeks.
Procedures
The outcome data were measured as follows the volumeter was placed on a horizontal stable surface and filled with tap water to the level of the spout. The patient was asked to lower his hand into the volumeter. This made the water to displace from the spout to be collected into a graduated glass container. The collected water in the graduated container which referred to patient’s hand volume was measured. For measuring hand grip strength each patient was instructed to start grip strength measures by using digital dynamometer, while elbow flexed 90 degree with hand and forearm in mid position and rested on the table.
•Thirty patients of both sexes (18 females and 12 males) who were diagnosed as stroke and referred by a neurologist. All of the participants complained from wrist and hand edema. The mean age was 54±7 years. They were selected from the out-patient clinic of the faculty of physical therapy, Cairo University. CT was performed for all patients to confirm the diagnosis. All patients had grade 1 to 2 of spasticity according to the modified Ashworth Scale10. Subjects were excluded if they had major cognitive impairment, heart failure, myocardial infarction, lymphedema, or trauma, . The patients were assigned into 2 groups equal in number group I which composed of 15 patients (10 females and 5 males ) and they received (IPC) .Group II composed of 15 patients (8 females and 7 males ) and they received (NMES).

The data were descriptively analyzed by calculating: Mean ± Standard deviation. Student t. test was used to compare the mean of pre and post study measurements of hand volume and hand grip strength in each group .The statistical significance difference was determined with P value d”0.05.Unpaired t.test was used to compare these findings between study groups.

applied over this and attached to the compression pump. The pressure levels were set as an intermittent compression manner which composed of a pressure of 80-120 mmHg for 40 seconds as compression phase and a pressure of 40 mmHg for 20 seconds as deflation phase 1.Each patient in both study groups received treatment once a day, 3 sessions weekly for 12 weeks.
All patients received the same standard physical therapy treatment designed for stroke patients, for 30 min on 3 days each week for 12 weeks, respectively. Group I patients received (IPC) therapy as follows, a stockinet layer was applied to the hemiplegic limb to absorb moisture and a full arm-inflatable sleeve was
or to prevent abnormal muscle reaction due to weakness and spasticity7 .It was found that application of (NMES) had a significant effect in reducing hand edema post stroke because it produce an active muscle pump resulted in removing excess fluid 8-9. Others studied the application of intermittent pneumatic compression (IPC) in treating hand edema following stroke but they found that (IPC) had a limited role in reducing edema if it used solely1. The aim of this study was to evaluate and compare between effect of application of (NMES) and (IPC) on reducing hand edema and improving hand function in stroke patients.

Because there was great contradictions about the effect of both IPC and NMES on reduction of edema in stroke patients’ hand . So, this study was conducted to help in determination the most effective modality with more prolonged effects on the edema of the hand in stroke patients. The study was performed on 30 stroke patients (18 females and 12 males) complicated with hand and wrist edema. Group I received therapy, while group II received (NMES). Both groups underwent their programs 3 times a week for 12 weeks. The collected data included values of hand, wrist volumes and hand grip strength which were measured before and after the treatment program.
Edema of the hand is one of the complications that can developed after stroke. The etiology of edema formation might be due to dependency and loss of muscle pump efficiency due to hemiplegia will hamper the return of blood in the veins of the affected limb20.
V- Correlation between hand volume and hand grip strength in both study groups:
Looking for group I, showed reduction of mean value of hand volume from the statistical analysis of data of group I showed improvement of hand edema after three months of treatment.
It can also be due to the increased venous and lymphatic return as a result of external pressure on a limb. This external compression not only moves the lymph and fluids along, but also it may spread the intercellular edema over a larger area, enabling more lymph and venous capillaries to become involved in removing the plasma proteins and water 21.

**highly significant * significant
These results can be attributed to the evidence that (IPC) increases venous velocity, reduces edema, enhances fibrinolytic activity and reduces the damaging effect of white cell activity13
The results of this study agree with (Armstrong and Nguyen 2001 )19 who reported that pneumatic compression is an effective tool for the reduction of edema.On the other hand there was contradiction with (Roper et al,1999) 1 in his previous study for the treatment of the edematous stroke hand with intermittent pneumatic compression (IPC)using a pressure of 50 mmHg, applied with 30 sec inflation and 20 sec deflation duty cycle treatment comprised daily for 1 month. This study showed no influence neither on edema reduction nor upper limb function. It seems that good results in our study were obtained because we used higher pressure levels (a pressure of 80-120 mmHg for 40 seconds as compression phase I
The mechanism of improving hand edema by the use of intermittent pneumatic compression therapy can also be explained as intermittent high pressure compression allows limb salvage in patients with hemostasis and limb-threatening ischemia who are not candidates for revascularization.14
RECOMMENDATION
Concerning group II neuromuscular electrical stimulation, their data showed reduction hand volume. However the reduction in hand edema in group II may be resulted from production of an active muscle pump which cause removing excess fluid during application of neuromuscular stimulation induced contraction of the paralyzed muscles 7. Also, application of neuromuscular stimulation resulted in increased muscle bulk and strength. This will also lead to greater capillary density and therefore improved local blood supply and tissue condition17. Neuromuscular electrical stimulation had also been reported to modulate edema by reducing capillary permeability22
Thissurvivors.findingwas also supported by previous study, which reported reduction in hand volume due to compression and squeezing of venous and lymphatic vessels caused by skeletal muscles contraction that results from the electrical stimulation. These repetitive contractions may promote reabsorption of leakage fluid and proteins with subsequent edema reduction11.

The purpose of this case study was to compare the effectiveness of traditional physical therapy interventions of using therapeutic modality and exercise versus a combined approach using mobilization with movement and exercises in the treatment of shoulder impingement syndrome. A total of 5 patients diagnosed with shoulder impingement syndrome were selected from the hospital. Patients then participated in the programs, which were held twice a week for two months. Main outcome measures included 24-hour pain (VAS), shoulder active range of motion (AROM), and shoulder function (SPADI). Repeated-measures analysis indicated significant decreases in pain, improved function, and increases in AROM. The MWM had a higher percentage of change from pre- to posttreatment on pain measures pain (VAS): 0.6 to 0.2 following 4 session treatment, higher percentage of change on the SPADI and in AROM.

ABSTRACT
Shoulder impingement syndrome, the most common diagnosis of shoulder dysfunction1, is often de-scribed as shoulder pain exacerbated by overhead activities. Primary shoulder impingement occurs when the rotator cuff tendons, long head of the biceps ten-don, glenohumeral joint capsule, and/or subacromial bursa become impinged be-tween the humeral head and anterior ac-romion. Primary impingement may be due to intrinsic factors: rotator cuff weak-ness2, chronic inflammation of the rota-tor cuff tendons and/or subacromial bursa, rotator cuff degenerative tendi-nopathy, and posterior capsular tight-ness leading to abnormal anterior/supe-rior translation of

the humeral head. It may also be due to extrinsic factors: possession of a curved or hooked acro-mion, acromial spurs, or postural dysfunction. Secondary shoulder im-pingement is defined as a relative de-crease in the subacromial space due to glenohumeral joint instability or abnor-mal scapulothoracic kinematics. Commonly seen in athletes engaging in overhead throwing activities, second-ary impingement occurs when the rota-tor cuff becomes impinged on the poste-riorsuperior edge of the glenoid rim when the arm is placed in end-range ab-duction and external rotation. This posi-tioning becomes pathologic during excessive external rotation, anterior cap-sular instability, scapular muscle imbal-ances, and/or upon repetitive over-load of the rotator cuff musculature. Physical therapy has been found to be effective in reducing pain and disability in patients with shoulder impingement. Effective interventions include therapeutic exercises focusing on strengthening the rotator cuff and scapular stabilizing musculature 3 , stretching to decrease capsular tightness, scapular taping techniques, and patient education of proper posture.

DISCUSSION
DVsMobilisationmeanswithMovement
The purpose of this case study was to describe the effect of exercise therapy combined with manual therapy in treatment of patients with shoulder impingement. It appears that the combined intervention of manual therapy and exercises for five weeks provided significant reductions in pain measures in subjects to those received only modality and exercise alone. It is important to note that the patients underwent traditional physiotherapy for an extended period with minimal improvement. Where as in patients who had undergone physical therapy intervention of manual therapy and exercise their end of treatment assessment score reflected improvement in the symptoms such as significant difference in the VAS, SPADI and AROM. Thus the combined treatment of manual therapy and exercises has proven to be effective in management of shoulder impingement syndrome.
CONCLUSION
The present study was conducted on five female patients, aged 32-45 (mean 39.8 years) with chief complaint of intermittent catching pain on shoulder, complaint of night pain and unable to sleep on involved side, who were diagnosed as having shoulder impingement syndrome. The effect of treatment was assessed based on the following dependent variables: pain intensity measured with VAS scale; pain-active ROM measured with a standard goniometer for flexion and abduction; and a measurement of shoulder function assessed with the Shoulder Pain and Disability Index (SPADI)4-5. These traditional interventions included TENS, posterior capsule stretching, postural correction exercises, and an exercise program focusing on rotator cuff strengthening and scapular stabilization. A manual therapy approach to treating shoulder dysfunction is the Mulligan concept of mobilization with movement (MWM)6. The goal of per-forming MWM is immediate and sus-tained improvement in joint pain and mobility. Mulligan’s techniques 6 entail having the physical therapist apply an accessory mobilization to a peripheral joint while the patient simultaneously generates active movement. This procedure was repeated for a total of 3 sets of 10 repetitions as long as pain-free motion was sustained; if pain commenced during any repetition of any set, the technique was terminated. This technique involved the therapist applying a sustained posterior accessory glide to the glenohumeral joint while the subject simultaneously actively flexed the shoulder to the pain-free endpoint and applied a gentle overpressure force using the contralateral arm. Total abolition of pain during the technique was mandatory; if the patient started to experience pain during active motion, the therapist would investigate different force planes and/or grades of force until pain-free motion was restored.

In summary, the physical therapy inter-ventions of Manual therapy base on MWM in combination with an exercise program resulted in decreasing pain and improving function compared to traditional physical therapy intervention.

Results: A significant association was noticed between age and wrist pain and no significant association was observed between gender, onset of pain and wrist pain. Higher frequency of back pain was noticed in older age group compared to younger. Neck pain was found to be higher among participants between 60-69 years of age. The incidence of pain in the wrist was more in men than in women and a similar pattern was seen in hand and back pain too. Our study shows a positive relation between sleep hours and musculoskeletal pain.

Musculoskeletal disorders (MSDs) are highly prevalent; because of their association with aging, they are likely to become more prevalent as the population ages throughout the world. While many of these disorders are not devastatingly disabling to affected individuals, their prevalence is so great that more mobility and other limitations are accountable to these disorders than to any other type. While much of the substantial cost of these disorders is due to the medical care and medications and other treatments required by patients, the preponderance of costs is due to work loss, which is a frequent consequence of these disorders. Not only do MSDs cause personal suffering and loss of income, but they also cost businesses and affect national economies. Any worker can be affected, yet MSDs can be prevented by assessing work tasks, putting in place preventive measures, and checking that these measures stayMosteffective.work-related MSDs are cumulative disorders, resulting from repeated exposure to high or low
INTRODUCTION
Conclusion: We concluded that wrist, neck and back pain is more prevalent in younger age groups and it increases as the duration of computer use increases. Pain was a problem in majority of people working on computer for more than 5 hours.

These disorders mainly affect the back, neck, shoulders and upper limbs, but can also affect the lower limbs. Some MSDs, such as carpal tunnel syndrome in the wrist, are specific because of their well-defined signs and symptoms. Others are nonspecific because only pain or discomfort exists without evidence of a clear specific disorder3. Different groups of factors may contribute to MSDs, including physical and biomechanical factors, organizational and psychosocial factors, individual and personal factors .These may act uniquely or in combination.
An integrated management approach is necessary to tackle MSDs. This approach should consider not just the prevention of new disorders, but also the retention, rehabilitation and reintegration of workers who already suffer from MSDs4 Individuals with musculoskeletal complaints should be evaluated with a thorough history, a comprehensive physical examination, and, if appropriate, laboratory testing. The initial encounter should determine whether the musculoskeletal complaint is (1) articular or nonarticular in origin, (2) inflammatory or noninflammatory in nature, (3) acute or chronic in duration, and (4) localized or widespread (systemic) in distribution 5 . The present study was conducted to assess the musculoskeletal problems among computer users and rationalize the variables that play a part in the occurrence of the pain and, to
assess the knowledge of face such problems and, to evaluate the measures taken to tackle and prevent musculoskeletal problems.
This descriptive study was conducted in the following settings viz. Ajman chamber of commerce building, Alco Shipping Services (Ajman), TNT branch (Deira), Ocean View Real Estate (Dubai), Oman Insurance (Ajman branch), AMB constructions, Gulf Chain, GMU and GMCHRC. Total 249 employees in the above settings participated in the study and the data was collected from 2009 March to 2010 January. We selected all those people who mentioned wrist, back or neck pain without any pre-existing musculoskeletal problems and those who work on computer for 5 hours or more. All those who had previous musculoskeletal problems, and who work less than 5 hours on the computer were excluded. A questionnaire was used for data collection including variables like Age, Sex, Nationality, Smoking status, Alcohol status, Diabetes, People with Wrist, Back and Neck pain.

MATERIALS AND METHOD
The questionnaires were distributed to different offices, selecting one office at a time to those who used the computer for 5 hours or more and the completed questionnaires were collected within two – three days. The whole process was repeated in all the above mentioned offices. The data from the questionnaire was then entered in an excel sheet and analyzed using PASW 18.0 version.

Through our study showed that there was a higher incidence of pain among the males and females although affected were not so severe. The incidence of pain in wrist to be more in men (61%) than in women (39%) and a similar pattern was shown in the hand and back pain too. This was not in confirmation with the other studies that we had gone through on MSDs. A study done in Europe found a higher prevalence of disorders in women (45%) than men (39%). This difference could have occurred in the study as they used a larger population for their study whereas our sample size was comparatively smaller. Our study shows a positive relation between sleep hours and musculoskeletal pain similar results was seen in a study by the psychosomatic research7
As the continuing use of machines and computers increases in today’s world there is a need for the general masses to be educated about the increasing incidence of musculoskeletal disorders. Many people have the tendency to overlook all these hazards as trivial and do not get it checked and hence end up with a series of mechanically restricting injuries.

DISCUSSION
MSD ranks first in prevalence as the cause of chronic health problems, long term disabilities and consultations with a healthy professional and ranked second for restricted activity all day and use of prescription medications and drugs. Hence society has come up with the intervention of ergonomics among the working masses.

41% of population who exercised twice a month suffered from wrist pain whereas approximately 37% of the population who exercised 4 times a month suffered from back and neck pain.(Fig-6)
CONCLUSION
There were many factors that we had to take into consideration for the completion of our study. These were Age, Nationality, Sex, Duration of work, Sleep hours, Pain intensity, Exercise, Diet, Smoking / Alcohol etc. Average duration of computer use in our study was 5 hours. This was in accordance with Bureau of Labour Statistics which said that average time of employees working on computer is 35 hours per week6
From our study we concluded that wrist, neck and back pain is more prevalent in younger age groups and it increased as the duration of computer use increased. The variables, age, duration of computer use, facilities at work place, sleep hours, diabetes and job satisfaction did play a part in occurrence of pain. The result showed that the commonest complaints were back pain and neck pain. Wrist pain was the least complained when operating on a computer system. Pain was more severe in people working for more than 5 hours. The result of this study can help in preventing occupational injury associated with the use of computer with emphasis on good posture, work station ergonomics.

CASE REPORT
Study design: A case report of a patient with Traumatic Central Cord Syndrome (TCCS)
Traumatic Central Cord Syndrome (TCCS) is the most common incomplete Spinal Cord Injury (SCI) with the incidence varying from 15.7% to 25%.1 As the lower limbs (LL) are less affected, early gait training can be initiated. However, poor trunk control is a major obstacle in achieving this goal. This can be overcome by stabilizing the trunk using a body weight supported approach.Todate,
only a limited number of studies have compared the benefits of task specific activities like body
ABSTRACT
Methods: A 25-year old man with TCCS at the C4 level, grade B on the American Spinal Injury Association (ASIA) Impairment Scale (AIS) participated in BWSOT. Following the immobilization phase, he underwent two BWSOT sessions per day (20 minutes each), six days a week, for three weeks. AIS motor score, 10-m walk test, Walking Index for Spinal cord Injury-version II (WISCI-II), Spinal cord Independence Measure-version III (SCIM-III) and Functional Independence Measure (FIM) were recorded at the time of initiating of BWSOT and at the end of three weeks. He received regular physiotherapy and occupational therapy during the entire hospital stay.
Conclusion: BWSOT may allow therapists to initiate gait training programs at an earlier stage among those with stable TCCS with promising outcomes.

A 25-year-old male presented with severe neck pain and quadriplegia after sustaining a fall from a height of 15m. He was managed conservatively and referred to the Neuro Rehabilitation Unit within 24 hours of injury. The patient was examined at the time of referral by a qualified physiotherapist. His vitals were stable. Neurological examination revealed normal higher functions and cranial nerves. His tone was flaccid in the upper limbs (UL) and increased in the LL at this time. Sensory and muscle power evaluation revealed a sensory and motor level of C4 with sacral sparing. American Spinal Injury Association Impairment Scale (AIS), motor score was 10/100 comprising 0/50 for UL and 10/50 for LL. Using AIS he was graded as AIS B. Deep tendon reflexes were absent in the UL and brisk

Fig 1 shows the BWSOT which consists of overhead suspension system and harness to support a percentage of the patient’s body weight as the patient walks on a parallel bar and progressively decreasing the amount of body weight supported as the gait pattern improves. The body weight unloading is high in the beginning of training and decreased gradually. The harness was attached to an overhead suspension, usually a system composed of ropes and pulleys (rope-and-pulley system) connected to a counterweight. A counterweight was used to dynamically unload part of the patient’s body weight.

Neck pain is very commonly shown by most people to be in the region of the back of the neck and between the bases of the neck to the shoulder, primarily indicating the region of the trapezius muscle1. About two thirds of people will experience neck pain at some time.2,3 Prevalence is highest in middle age with women being affected more the men. The prevalence of neck pain varies widely between studies, with mean point prevalence of 13% (range 5.9 – 38.7%) and mean lifetime prevalence of 50% (range 14.2 – 71.0%).

Effects of Ischemic Compression on the Trigger Points in the Upper Trapezius Muscle
Method: 30 subjects were randomly assigned to either treatment group (group 1) or a control group (group 2). Subjects in group 1 received ischemic compression on the primary trigger point followed by stretching of the upper trapezius muscle. Subjects in group 2 received active neck exercise followed by stretching. All the patients of group 1 and 2 received treatment for 7 days. Pressure Pain Threshold (PPT) measured by pressure algometer was used to measure trigger point sensitivity and Visual Analogue Scale(VAS) was scored as a measure of pain intensity on day 1 and day 8 in both the groups.
INTRODUCTION
Results: In the treatment group (group 1) significant improvement was evident in the pressure pain threshold values (t=7.02, p<0.05), however no such improvement was found in the control group (group 2). Comparison between the two groups also showed significant difference in the pressure pain threshold

was noted in the visual analogue scale score of group 1 (T=120, p<0.001) and group 2 (T= 66, p<0.001) both; however greater improvement was noted in treatment group (group 1).
Conclusion: Ischemic compression technique is highly effective in reducing the trigger point sensitivity and pain intensity in the trapezius muscle.
-A palpable tender spot in the neck or upper back
The subject was required to complete the informed consent form. Then the subject was asked to mark a visual analogue scale with the average pain intensity for their pain over past 24 hours. The subjects were then acquainted with the sensation of pressure algometer on an unaffected part of the body before testing for pressure pain threshold of primary trigger point. The pressure algometer was placed perpendicular to the area to be tested, increasing the pressure steadily at the rate of approximately 1 Kg/sec. Examiner palpated the region of trapezius and marked all the trigger points that matched the inclusion criteria with a non permanent marker. Pressure pain threshold was measured for each marked trigger point. The trigger point with the lowest pressure pain threshold was considered as primary trigger point and was marked with Reynolds permanent marker.

not produce muscle soreness. However due to difference in study population and outcome measures used to assess the effectiveness, there is lack of rigorous evidence for use of ischemic compression in clinical practice. The objective of the study is to determine the effectiveness of ischemic compression for the treatment of myofascial trigger points in upper trapezius.

All the patients of group 1 and 2 received treatment for 7 days. No treatment was given on the 8th day to determine the short term effects of the intervention without confounding effects from the treatment just completed. On day 8, the therapist again obtained measurements for each subject A Pressure Pain Threshold measurement of primary trigger point and a visual analogue scale score for the average pain intensity for the past 24 hours were recorded.

et al found injection of a local anesthetic, injection of a local anesthetic plus steroid, acupuncture (dry needling), and acupressure with vapocoolant spray to be effective in relieving pain.8 This conclusion is also supported by authors like Rubin D (1981)12 Imich D et al (2002)24 and Hong C (1994)9. Garvey et al reported that the acupressure plus vapocoolant spray was the most effective at relieving pain. This led them to propose that relief is likely due to mechanical stimulation of the trigger point by the needle or the acupressure, not the injection of a particular substance. Hong C also suggested that, local vasodilatation and removal of metabolites along with mechanical disruption of abnormal functioning of contractile elements or nerve endings is responsible for trigger point inactivation by injection method. However the treatment involves invasive procedure and to the varying degree produces post injection soreness and muscle necrosis.

The present study demonstrates significant improvement in pain intensity and pain threshold in group 1 treated with ischemic compression and trapezius stretching compared to group 2 treated with active neck exercises and trapezius stretching. Research in 1993 by Hong et al lends credibility to the statement that ischemic compression is superior to other physical medicine modalities for treating trigger points. Similar result has been obtained by Jamie Dearing (2007)28

Limitations And Future Suggestions
When ischemic compression is used on the trigger points, local chemistry changes due to blanching of the nodules followed by hyperemia when the compression is released. This flushes out the muscle inflammatory exudates and pain metabolites, breaks down the scar tissue, desensitizes the nerve endings and reduces the muscle tone. Thus the ischemic compression has essentially the same mechanism of action on the trigger point as the injection therapy. However ischemic compression is a non invasive technique that

does not produce post treatment soreness or hemorrhage.Stretching of the affected muscle is believed by some -authors to be an integral part of trigger point therapy. 6,10,13,14,25 Techniques like post isometric relaxation, strain/ counter strain, reciprocal inhibition, passive stretching of the affected muscle and ‘spraystretch have been found to be effective in reducing the pain intensity and trigger point sensitivity.7,18,26 Simons (1981) hypothesized that stretching a muscle releases the locked actin and myosin heads, allowing the ATP to form. The ATP allows the sarcoplasmic reticulum to return to normal and circulation to improve.27 However the stretch works better when there are nerve impulses from the skin being sent to the brain and inhibiting the reflex pathway that produces trigger point activity and pain messages. These conflicting skin impulses are most viewed as a sustained stretch to a specific point in the muscle and it gets right to the tight or restricted area in a muscle. The conclusion would seem to be that stretching alone is not enough but that as an adjunct to ischemic compression it is helpful.
DISCUSSION
The study did not examine effectiveness relative to any other outcome such as functional limitation or disability.Thelong
The results of this study indicate that ischemic compression is highly effective in the short term management of trigger point in the upper trapezius by reducing the trigger point sensitivity and average pain intensity.

Point prevalence of neck pain is nearly 13%19,20 and lifetime prevalence is 50%.21 In females, the fiber-type distribution pattern of trapezius is similar to male but the mean cross-sectional area of the fibers is considerably smaller. The significantly smaller crosssectional fiber area, which indicates a lower functional capacity, may be of importance in the development of neck and shoulder dysfunction in females. 22 Researchers also found that shoulder abduction torque and trapezius EMG amplitude were significantly lower in the women with myalgia compared with those without the muscle pain.23 Higher incidence of neck pain in female population can be accounted for the higher number of female subjects in the present

ABSTRACT
Results: Of the 72 subjects 93.1% had upper limb dysfunction as determined by the test scores. The mean and standard deviation of SAMP score for the right hand was 20.44 ± 5.25 and for the left hand it was 18.49 ± 4.49. The comparison between the mean scores of right and left upper limb was done to show a cumulative finding using one sample t- test and it was found to be statistically significant (p < 0.001).

INTRODUCTION
Study design: Cross sectional study
Method: Seventy two (72) subjects fulfilling the inclusion criteria and exclusion criteria were taken up for the study. The upper limb dysfunction was measured for all the subjects for both the hands. Descriptive statistical analysis was carried out for this study. Results on continuous measurements are presented on Mean SD (Min-Max) and results on categorical measurements are presented in Number (%) with level of significance set at 0.05. The comparison between the categorical measurements has been analyzed using one sample t- test.
Objective: To find out the prevalence of upper limb dysfunction in subjects with non specific neck pain. Summary of the background data: Non specific neck pain is highly prevalent in women particularly of working age. Upper limb disorder and disability/ dysfunction are one of the most important factors that have been discovered in the management outcome for nonspecific neck pain. Single Arm Military Press (SAMP) test has been used to measure the level of upper limb dysfunction in neck pain population. With a high prevalence of non specific neck pain in India either due to their occupation or age it becomes important to quantify the rate of upper limb dysfunction in Indian population in their working environment so that further measures can be taken to address upper limb dysfunction in the course of management of non specific neck pain.

Exclusion criteria
A set up was organized taking the participants privacy into consideration in the various working institutions for the study. Three kilogram dumbbell and a stop watch along with documentation sheet were arranged.
Despite the high prevalence of neck pain in India, limited literature is available regarding the presence of upper limb dysfunction among neck pain population. Thus, the present study intends to find out the prevalence of upper limb dysfunction among subjects with non specific neck pain by evaluating the strength and endurance of upper limb using SAMP test.

Procedure of data collection
A cross sectional study on 72 symptomatic subjects with non specific neck pain was carried out in various institutions in Bangalore city, India. The institutions included primary and secondary school, private workplace, private hospitals and clinical diagnostic centres. An ethical clearance for Research study was obtained from M S Ramaiah Medical College and Hospital, Bangalore, Karnataka, India. Approval for conducting the study was taken from the Principals of
To assess the baseline dysfunction of upper limb in subjects with neck pain a performance based outcome measure was used viz., Single Arm Military Press (SAMP) test. This SAMP test has a cut off point i.e. 25. This means that the scoring less than 25 was considered to be having upper limb dysfunction amongst the subjects and a score of 25 and above meant the subject did not have upper limb dysfunction.

the respective institutions. All the participants were provided with a copy of the detailed informed consent form. Purpose of the study was explained and a written informed consent was obtained from the subjects. Seventy two women of age ranging between 30 to 55 years fulfilling the inclusion criteria and exclusion criteria were taken up for the study. Following a formal introduction, a brief demographic data of the subjects participating in this study was noted. The procedure of the SAMP test was explained and demonstrated. This test required the subjects to complete as many repetitions of the SAMP technique as possible within 30 seconds using a 3kg weight [see figures (1) and (2)] with both the upper limbs separately. All participants were instructed to do the test as fast as possible but could stop and start at anytime during the 30 seconds, though the timing continues. This was one time performed technique and the cut off number of repetitions was 25, the number of repetitions subjects were able to do was documented.

DISCUSSION/CONCLUSION
•Further validating the clinical use of SAMP test as an outcome measure of upper limb dysfunction/ disability.
Studies have shown that with increase in age there will be a steady drop in SAMP test score11 and the assessment of work and non work related factors particularly in women is essential18. Since the present study was just to find the prevalence of upper limb dysfunction in non specific neck pain population, no other outcome measures were used other than SAMP test. This study suggests performing a detailed biomechanical and functional analysis of the specific area of problem (neck) as well as associated part (upper limb) of the musculoskeletal system, in order to plan out a rehabilitative protocol / strategy for any working individual with neck pain.

Materials and Methods: 40 women with chronic genuine stress incontinence were randomized into Group A - where women were delivered the pelvic floor muscle exercises in a group of 10 (n=20) & Group B - where pelvic floor muscle exercise on a conventional one to one basis, the individual approach (n=20) were administered. Outcome measures which included VAS for measuring severity of incontinence & King's health questionnaire for assessing quality of life were taken at baseline & at the end of 3 months intervention program.
ABSTRACT
Although not a life-threatening condition, GSI causes various physical, psychological & sexual problems for millions of women & their families. GSI thus has a negative impact on Quality of Life (QoL) & most affected domains are physical health & mobility.4 Hence the need for the effective management of this condition is vital, not only for the relief of symptoms but perhaps more importantly, for the prevention of recurrent episodes of leakage, personal suffering, and lost work productivity.Studieshave
Results: Both the group A and group B showed improvement in severity of incontinence and quality of life postintervention when compared with preintervention measurement and 't'calculated value for pre-postintervention measures was statistically significant as it was above the 't' tabulated value. Moreover, Mean±SD of pre-post change in VAS for group A was 2.02±0.46 and for group B was 1.94±0.43 and King's Health Questionnaire scores for group A was 30.09±5.3 and for group B was 21.51±6.73. 't'calculated value for pre-post changes was statistically not significant as it was below the 't' tabulated value of 2.576.
GSI (Genuine stress incontinence); also known as Stress urinary incontinence is defined as an involuntary loss of urine that occurs during physical activity, such as coughing, sneezing, laughing, or exercise.1 GSI is found to be commonest, with its prevalence being greatest in 5th decade of life.2 WHO’s 1st International Consultation on Incontinence estimated that bladder
problems affects approximately 200 million people worldwide, with 10 to 30% of women between the ages of 20 and 55 years, and in up to 40% of older women.3

Session 6
In this Experimental study, total of 40 subjects who were sent to Bombay Maternity and Surgical Hospital, Surat were assessed for their eligibility based on the criteria for the study and following that they were randomly assigned to Group A & Group B. After signing the written informed consent (to participate in the study and to allow reproduction of their photographs) they were made to participate in study and baseline measurements were recorded.
Inclusion criteria
Session 2
Session 4
Exercise Regimens
PFME in standing position with different foot positions taught.
Recruitment of transverse abdominus along with PFME taught.
Group met for nine, one-hour long sessions over a three months period. Group sizes were planned to be 10 women in a group.
Introduction to anatomy of lower abdomen & pelvic floor, explanation of normal PFM & bladder function, teaching and practice of PFME’s recruiting both fast & slow twitch fibers, encouraged to maintain contraction for 3-5 seconds, repeat 10 times.
This PFME can be given on a one to one basis as with the conventional ‘individual approach’ or can be given simultaneously to a group of women; a ‘group approach’. Promoting incontinence in group sessions is suggested as an effective means to educate women & to encourage active self-management. Approximately 20% of Women’s Health Physiotherapists use group approach.9 Despite this there has been few Randomized Control Trials comparing the effectiveness of group intervention against individual approach which signifies the need of the present study. Thus the aim of the study was to compare the effectiveness of pragmatic group approach versus individual treatment sessions on the severity of incontinence & QoL in patients with GSI.

GROUP AGROUP B
Following a 3 months intervention with Group Physiotherapy sessions & Individual Physiotherapy sessions, the women showed significant reduction in severity of incontinence & improvement in QoL. However there were no significant differences found between the two groups treated individually or in group, thus suggesting that both individual & group physiotherapy sessions are equally effective in management of women with GSI. These findings are in line with the findings of previous studies done by Sara Demain et al. (2001),9 Janssen et al. (2001)11 & Flavia Camargo et al. (2009).12
1.This study only included women with GSI between age group of 30-55 years as GSI is most common in that age women & also a big age difference in women receiving group therapy may lead to improper delivery of exercise to patient.
2.This study only included a smaller population as study sample & also the time duration chosen was limited, thus giving only short-term benefits.
As seen from our study, while considering QoL it can be seen that some domains of QoL like physical limitations, social limitations and personal relationships showed improvement better in group than individual sessions. This can be attributed to better delivery of information in group sessions and hence high level of satisfaction associated with group therapy as suggested by B Aston et al. (2007).15 Previous works done by Frances Griffiths et al. (2009)16 showed that women who had preference for individual therapy when given group sessions exhibited their experience of group sessions as good but also stated that for group sessions, its effectiveness lies in its proper designing. If the designing of group therapy is not proper than embrassement associated with group sessions may lead to failure in delivery of effective treatment.

DISCUSSION

Future Implications
Moreover, both the strategies being equally effective, group therapy can be considered as a convenient option as it may be more cost effective, but the cost-effectiveness of group therapy needs to be assessed. The findings of studies done by LA Hill et al. (2007)13 and SE Lamb et al. (2009)14 showed cost-effectiveness of group therapy and hence gave preference towards it.

ABSTRACT
A Study of Electromyographic Changes in Muscle Post Exercise Induced Muscle Soreness
INTRODUCTION
The muscle soreness usually manifests as a dull, aching pain combined with tenderness and stiffness. Clinical signs of muscle soreness include increases in plasma enzymes12, 14, 16 muscular fiber degeneration, 17 and the protein degradation18 that accompanies the degeneration to favor sarcomere disruption as the starting point for the damage. As well as damage to muscle fibers there is evidence of disturbance of muscle sense organs and of proprioception.19

Results: The mean value of peak EMG of Rectus Femoris pre exercise is 508.69mV (microvolt) and post exercise induced muscle soreness is 686.60 mV. The mean of peak EMG amplitude of Vastus Medialis Obliqus came out to be as 379.81 mV pre exercise and 472.70 mV post exercise induced muscle soreness. The p value for RF pre and post was 0.000 and for VMO pre and post was 0.034.
Aim and objective: To analyze electromyographic changes in muscle post Exercise Induced Muscle Soreness (EIMS).
At one time or another, each one of us must have experienced muscle soreness following everyday activities that are not associated with participation in sports or in formal exercise programs for e.g.: downhill walking etc. Although muscle soreness usually occurs in less physically trained individuals, most people, including elite athletes can experience this soreness as well. Since the soreness is experienced in the time period following any strenuous work, it is termed as exercise induced muscle soreness (EIMS).

Accompanying the muscle soreness is muscle weakness”20, 21 which persists long after the muscle
Exercise-induced muscle soreness is a common occurrence in daily routine. It can be classified as acute or delayed onset muscle soreness.1-4. Acute onset occurs during exercise and may last four to six hours postexercise before subsiding. Delayed onset muscle soreness (DOMS) typically appears approximately 12 hours after activity and may last for several days following exercise.1,2 It is perhaps one of the most common and recurrent forms of sports injury.2
Methodology: 80 subjects(age group 21-30yrs, BMI 18-29kg/m2) free of any musculoskeletal/ Neuromuscular/psychological disorder, took part in the study. After checking for leg dominancy and calculation of BMI, the subjects were asked to perform one single squat up to 900 of hip and knee flexion while an EMG of the Rectus Femoris and Vastus Medialis Obliqus (both parts of quadriceps muscle) was recorded simultaneously. Another EMG reading was taken in the similar manner after confirming the development of muscle soreness on a graphic pain rating scale following the exercise protocol.
All forms of exercise, if carried out vigorously enough, can become painful. But only one form of exercise, eccentric exercise5, 6, if we are unaccustomed to it, leaves us stiff and sore the next day. In eccentric exercise the contracting muscle is lengthened; in concentric exercise it shortens. These eccentric actions produce micro-injury to the active muscle fibers, 7-10 exhibiting muscular soreness, loss of joint range of motion, swelling, and decreased force production.8, 11-16

The quadriceps Femoris muscle plays an important role in explosive and powerful actions of the leg during sport and daily activities. Eccentric contraction is commonly used during training programs which often leads to fiber injury and muscle soreness.

METHODOLOGY
Exclusion Criteria
1.Neurotrac EMG machine
A measure to quantify muscle soreness is a Graphic pain rating scale33 which is a 12 cm line between no pain and unbearable pain. Pain was quantified by measuring the distance (to the nearest 1/2 cm) from the extreme left to the mark made by subjects to describe their perception of pain. The length was multiplied by two, yielding scores from 0 = no pain to 24 = unbearable pain.Electro-myography
AIMS AND OBJECTIVE
(EMG) is the study of muscle function that involves recording the action potentials (or electrical currents) that activate skeletal muscle fibers23, 24

There is significant change in EMG analysis of quadriceps muscle post exercise induced muscle soreness.
After fatiguing muscle with exercise, there is a decrease in maximal force production, which has been observed as early as l hour after exercise. The surface electromyographic (EMG) activity is modified during muscle Fatigue (Big1and-Ritcgie, 1981).The EMG power spectrum is shifted towards the lower frequencies as exemplified by the fall in mean power frequency (MPF) during static contractions as well as during dynamic exercise. The EMG spectrum from eccentric, concentric muscle contractions under human were studied as a factor of mechanical damage of muscle fiber and functional change of metabolic tissue. The primary purpose of the study was to examine the relationship between DOMS in after exercise and EMG change in during exercise. A secondary purpose was to examine their relationship to local muscle fatigue and perceived scale of DOMS. We hypothesized that if exerciseinduced muscle soreness is associated with muscle fatigue then the localized DOMS to muscle contractions would be accompanied by attenuated response in index of muscle fatigue.

1.Peak value of EMG amplitude
80 subjects volunteered for the study, out of which 61 subjects were fulfilling the inclusion criteria and 19 were excluded. The subjects who were fulfilling the inclusion criteria were explained about the topic of the research and its advantages and disadvantages. After clearing their doubts regarding the study, a written consent was obtained from them.
squat exercises with the final set including continuous squats as long as participants could complete an entire repetition. The exercises were terminated when subjects indicated that they were unable to perform the exercise furtherThe
The subjects were asked to kick a ball to check for leg dominancy29 and their body weight and height was measured for calculating the body mass index. The dominant leg was then prepared for the recording of the EMG. The skin was carefully prepared by rubbing with abrasive gel and alcohol. All standard precautions were taken before recording EMG activity of the muscle. The EMG activity of Vastus Medialis Obliqus (VMO), and Rectus Femoris (RF) (both parts of QUADRICEPS) was recorded with surface electrodes (5mm disk selfadhesive electrodes) placed approximately in parallel with the muscle fibers over the muscle bellies, based on a modification of standard proposed by Zipp30. The distances and angles were measured for optimal electrode placement.31
The mean value of peak EMG amplitude of Rectus Femoris (RF) pre exercise is 508.69mV (microvolt) and post exercise induced muscle soreness is 686.60 mV whereas for Vastus Medialis Obliqus (VMO) it came out to be as 379.81 mV pre exercise and 472.70 mV post exercise induced muscle soreness.
The mean percentage for RF pre is 43% and post is 57%
2.Graphic pain rating scale(GPRS)33
The subjects were asked to perform a single 2sec down and a 2sec up squat while the EMG was recorded simultaneously. After this the subjects were requested to perform squat exercises, specifically chosen to induce fatigue in the knee extensors (quadriceps) (William Retailer et al). An intermittent exercise protocol(Navrag B. Singh et al)32 was used and subjects were requested to start in an upright position with feet shoulder-width apart and with weights (approx. 40% body weight) carried on a barbell over the shoulders, squat down to approximately 90° knee flexion, and return to their start position. Each set of squat exercises consisted of eight repetitions and a 30 s rest period was provided between sets. Each subject performed a minimum of 11 sets of

subjects were then required to fill up Graphic Pain Rating Scale33 after 8hrs of the exercise session to assess for the induction of DOMS. Those in which DOMS were established were again asked to perform a 2sec down and 2sec up squat and the EMG was recorded. After recording the subjects were given ice packs and were advised to take ice packs at home twice daily for next five days for the treatment of the muscle soreness.Thesubjects were specifically not allowed to perform any vigorous physical activities or quadriceps muscle stretching or any form of treatment for muscle soreness during the entire experimental period34.

Thus the experimental hypothesis for the study holds true i.e; there is significant change in the peak EMG amplitude of the muscle post exercise induced muscle soreness.

A reduction in force output by an injured part of a muscle may lead to compensatory recruitment from an uninjured area of a muscle, or from other muscles35. This leads to a marked increase in EMG activity (hyperactivity), altered EMG ratios and increased force production of the compensating muscles.

Among various documented risk factors for LBP such as smoking 15 obesity 16, pregnancy 17, physical activity18, mental health 19, recent research done by Smith et al. 2009 and Hodges et al., 2007 has focused on the relationship between LBP and respiratory disorders,
It has been suggested that the overall mechanical stability of the spinal column, especially in dynamic conditions and under heavy loads, is provided by the spinal column and the precisely coordinated surrounding muscles. 10 The spinal stabilizing system of the spine was primarily suggested by Panjabi (1992), consisting of three subsystems: the spinal column providing intrinsic stability; spinal muscles, surrounding the spinal column, providing dynamic stability; and the neural control unit evaluating and determining the requirements for stability and coordinating the muscle response11,12 . Under normal conditions, the three subsystems work in harmony and provide the needed mechanical stability 13,14
Effect of Pelvic Floor Muscle Strengthening Exercises in Chronic Low Back Pain

Low back pain (LBP) is a condition of localized pain to the lumbar spine. The pelvic floor muscle (PFM) have an important role in proper muscular activation for lumbar stabilization and also in unloading the spine. It was hypothesized that PFM exercise could be of benefit for patients with chronic LBP. After ethical approval, a randomized controlled trial was carried out on 30 females with chronic LBP. Patients were randomly allocated into two groups: an experimental and a control group. The control group was given conventional physiotherapy treatment including modality and exercises; and the experimental group received PFM strengthening with conventional therapy for 5 times per week upto 4 weeks. Pain intensity and functional disability by Oswestry Disability Index were measured before and after intervention . In both groups pain and functional disability were significantly reduced following treatment (p < 0.01). Also the significant difference was found between the two groups (p > 0.05). It seems that the PFM exercise combined with conventional treatment was effective over conventional treatment alone in females with chronic LBP.
causes may include osteoarthritis, rheumatoid arthritis, degeneration of the discs between the vertebrae or a spinal disc herniation, a vertebral fracture (such as from osteoporosis), or rarely, an infection or tumor. In the vast majority of cases, no noteworthy or serious cause is ever identified. If the pain resolves after a few weeks, intensive testing is not indicated.9
ABSTRACT
INTRODUCTION
may be classified by the duration of symptoms as acute (less than 4 weeks), sub acute (4–12 weeks), chronic (more than 12 weeks).6 Causes of lower back pain are varied. Most cases are believed to be due to a sprain or strain in the muscles and soft tissues of the back.8 Others may have pain from their sacroiliac joint, where the spinal column attaches to the pelvis, called sacroiliac joint dysfunction.

Low back pain (LBP) is a condition of localized pain to the lumbar spine with or without symptoms to the distal extremities whose etiology is commonly unknown. 1 More than 80% of the population will experience an episode of LBP at some time during their lives. 2 For most, the clinical course is benign, with 95% of those afflicted recovering within a few months of onset. 3 Some, however, will not recover and will develop chronic LBP (ie, pain that lasts for 3 months or longer). Recurrences of LBP are also common, with the percentage of subsequent LBP episodes ranging from 20% to 44% within 1 year for working populations to lifetime recurrences of up to 85%. 4 In the United States it is the most common cause of job-related disability, a leading contributor to missed work, and the second most common neurological ailment — only headache is more

Sapsford et al. (2001) investigated the co-activation pattern of the pelvic floor and the abdominal muscles via needle electromyography (EMG) for the abdominals and surface EMG for the pelvic floor. They found that the abdominals contract in response to a pelvic floor
incontinence and gastrointestinal problems from the Australia.20 A longitudinal study on women’s health reported that women with pre-existing incontinence, gastrointestinal problems and breathing disorders were more likely to develop LBP than women without such problems. 21 This was considered to be a result of changes in control of the trunk muscles following involvement with incontinence, respiratory and gastrointestinal problems. Changes in morphology and altered postural activity of the trunk muscles including muscles of respiration and continence which provide mechanical support to the spine and pelvis has been shown to be related to the development and occurrence of LBP (Hides et al., 2001, Cholewicki et al., 2005).
MATERIALS AND METHOD
Apart from the role of pelvic floor muscle (PFM) in patients with urinary and faecal incontinence, the PFM have also an important role in proper muscular activation for lumbar stabilization and also in unloading the spine (Sapsford and Hodges, 2001, Sapsford et al., 2001). The pelvic floor forms the base of the abdominal cavity and during different tasks that elevate intra-abdominal pressure, muscles must contract to maintain continence and contribute to pressure increases (Gilpin et al., 1989). In a small experimental trial of healthy subjects, strong voluntary abdominal muscle contraction caused PFM activity at the same intensity as maximal PFM’s effort (Sapsford and Hodges, 2001). Morkved et al. (2007) have investigated the effect of group training during pregnancy in prevention of lumbopelvic pain. Selfreported symptoms of lumbopelvic pain, sick leave, and functional status were measured on 301 healthy nulliparous women who were randomly allocated into a training group (148) or a control group (153). The control group received daily PFM training at home, and the training group was given weekly group training over 12 weeks including aerobic exercises, PFM and additional exercises, and information related to pregnancy. They reported that at 36 weeks of gestation women in the training group were significantly less likely to report lumbopelvic pain and had significantly higher scores on functional status but there was no difference in sick leave during pregnancy. However, they concluded that a 12-week specially designed training program during pregnancy was effective in preventing lumbopelvic pain in pregnancy.
contraction command and that the pelvic floor contracts in response to both a “hollowing” and “bracing” abdominal command. The results from this research suggest that the pelvic floor can be facilitated by coactivating the abdominals and vice versa.
This experimental study was carried out in Physiotherapy OPD of Dr. D. Y. Patil College of Physiotherapy, Pune. Ethical approval was taken from Institutional Ethical Committee. 30 married females with chronic low back pain fallowing in the age group between 20 to 40 years were selected and divided by random allocation into two groups- group A with 15 females and group B with 15 females. Pregnant females, females with any Urogenital Dysfunction like UV Prolapsed, Pelvic Inflammatory disease, Nerve injury to pelvic floor muscle, any pathology of spine, lower limb were excluded from the study. Informed consent was obtained from all the females. Females from Group A received conventional physiotherapy treatment which included Short wave diathermy or Interferentional therapy , Abdominals and back extensors strengthening exercises, Stretching exercises along with core stabilizers (Transverse abdominals and multifidus) for 5 times per week upto 4 weeks.
Females from Group B received conventional physiotherapy treatment as mentioned above along with pelvic floor muscle strengthening exercises for 5 times per week up to 4 weeks.Pelvic Floor strengthening exercises were given initially in supine position. Before starting, patients were instructed to evacuate their bladder, relax as much as possible, not to hold breathing and concentrate only at pelvic floor muscles. Patient was instructed to contract pelvic floor muscles, hold the contraction for 5 seconds and then relaxation for 5 seconds. She was further instructed to repeat the contraction for 10 times. As the strength was increasing, contraction time was increased and relaxation time was
However, very few published evidence was found to assess the function of PFM in patients with LBP or to evaluate the effect of PFM exercises in the treatment of such patients. The need to carry out this study was to investigate the effect of PFM exercise in the treatment of patients with chronic Low back pain specially in females . As PFM has an important role in lumbar spine stability, and lumbar instability was suggested to be one of the causes for LBP, it was hypothesized that PFM exercise could be of benefit for patients with chronic LBP.

A study done by Eliasson et al. (2008) concluded that the prevalence of urinary incontinence and signs of PFM dysfunction were greatly increased in the LBP group compared with the reference group. It appears that LBP is a risk factor for urinary incontinence and assessment of PFM function may be of value when treating patients with LBP. Evidence suggest that the exercise of the abdominal muscles may be beneficial in maintaining PFM coordination, support, endurance, and strength. Hence these exercise has the potential to be useful in the rehabilitation of persons with symptoms of PFM dysfunction. A few studies by Sapsford et al., 2001 and Neumann and Gill, 2002 have demonstrated the synergy between abdominal muscles and PFM in healthy volunteers. EMG activity of PFM and abdominal muscles showed that during voluntary activity of PFM all abdominal muscles were activated at different levels. The PFM seems to be an integral part of trunk and lumbopelvic stability in addition to contributing continence. As there are the strong evidence supports the co-contraction of PFM and abdominal muscles, the results of the present study showed the consistent result that these co-contractions have an effect on patients with chronic LBP and reducing disability.

One of the functions of PFM is to unload the spine. The static pressure created by a rigid abdominal cylinder can act to support the upper part of the body and therefore unload the spine. This involves abdominal, dorsal, diaphragmatic and PF muscles( Grillner et at 1978). Studies also indicates that the co-activation of all these muscle is an essential prerequisite for developing appropriate IAP, thus supporting the spine. When strengthening of the PFM occurs, the load on the lumbar spine decreases. This may be the cause for reliving LBP in the present study.
Sapsford et al 2001 suggested that recruitment of abdominal muscles function in association with voluntary contraction of PFM may be affected by spine

position. Placing the lumbar spine in flexion or extension would change the length-tension properties of the abdominal muscles and may have an influence on their response to PFM contraction. As Sapsford et al. (2001) highlighted that increase in Transverse Abdominals activity with PFM activity was significantly greater compared with External Oblique and Rectus Abdominal in lumbar extension. It was suggested that a neutral or extended lumbar spine position is preferable for PFM exercise. In addition, these findings indicate that contraction of the PFM may be used to initiate contraction of the abdominal muscles. A RCTby Richardson et al., 1999 indicates that specific training of the Transverse Abdominals can assist with the management of LBP. The results of their investigation revealed that this could be best achieved by contraction of the PFM with the spine positioned in either a neutral or extended position. In the present study patients were instructed to perform PFM exercise in supine position ( Neutral Position). This can results in improvement in LBP by strengthening transverse abdominals.

Introduction: Hamstring tightness may result in several conditions of the knee and spine such as anterior knee pain and low back pain. Stretching is a preventive and therapeutic technique in these situations. The aim of this study is to compare the effectiveness of static stretching and hold-relax PNF on increasing the extensibility of hamstring muscles.

ABSTRACT
Findings: At the end of the treatment period, we found a significant difference in hamstring extensibility among the study groups. Hamstring extensibility was significantly larger in both treatment groups compared to the control group (p<0.001). Moreover, the subjects in PNF group showed significantly greater hamstring extensibility compared with the static-stretch group (p=0.015).
moment following hamstring tightness may cause anterior knee pain owing to excessive patellofemoral forces (1-2). Furthermore, decrement in rang of knee extension may result in plantar fasciitis due to abnormal loading on forefoot (3) . In patients with hamstring tightness, anterior pelvic tilt is decreased during trunk forward bending(4); therefore mobility in lumbar vertebrae would be increased(4), and lead to low back pain(4-6). Because of these problems, it is important to consider the length of the hamstring muscle group.
Comparing Hold Relax - Proprioceptive Neuromuscular Facilitation and Static Stretching Techniques in Management of Hamstring Tightness
Stretching is a preventive and therapeutic technique (7-8) which is applied musculotendinous structures in order to change their length, improve joint range of motion, reduce stiffness, improve performance, decrease risk of injuries, improve posture and promote relaxation(8-10). There are different types of stretching
Conclusion: The present study suggests that hold relax - PNF is more effective than static stretching in increasing the hamstring extensibility. Therefore, application of this technique and education of that may be more useful for either patients with hamstring contracture or athletes.
Method & material: 51 male subjects in the age range of 18 to 30 entered to the study and randomly assigned to one of the three groups of static stretching, hold-relax PNF and control. The extensibility of hamstring was assessed by Active Knee Extension Test (AKET). The treatments in both static stretching and PNF groups were applied for six sessions during the study.

The two-joint hamstring muscle group is the knee flexor and hip extensor. The complete range of knee flexion rarely occurs in activity daily living; therefore the complete contraction and stretching of this muscle group is rare. In this type of muscles, failure may be occur under rapid and stressful situations(1).

The subject was supine with his hip in 90 degree of flexion. Therapist passively extended the subject’s knee up to a point where the subject reported a mild to moderate stretching sensation without any pain. The therapist held this position for 30 seconds and then repeated the procedure three times with 10 seconds rest between successive stretches.
We recruited a convenience sample of 51 male subjects in the age range of 18 to 30, who were the students of a local university. Exclusion criteria were musculoskeletal or neuromuscular disorders, a history of fracture or dislocation in lower extremity and active participation in sports or exercise activities that required regular hamstring stretching. We defined active participants as those who were involved in regular exercise activities in at least 2 sessions during a week.
Extension Test (AKET) for this purpose. The subject lied in supine position with his hip and knee in 90 degree flexion and ankle in plantar flexion. Then, he was asked to extend his knee as far as he could and in this position, popliteal angle was measured by a goniometer. To measure this angle, a long-arm goniometer was utilized. One arm was located on the line connected the greater trochanter and the lateral femoral condyle.The other arm was along the line from the lateral malleolus to the lateral condyle of tibia.
MATERIAL & METHOD
techniques including static, active, passive, proprioceptive neuromuscular facilitation (PNF) and ballistic(7, 10-11). Static stretching is the most common form of stretching technique because of its safety, effectiveness and easy performance(10). PNF stretching involves active muscle contraction and neuromuscular reflexes which decrease the resistance against stretching(10, 12)
Static stretching group
Subjects
The subject was supine with his hip in 90 degree of flexion. The Therapist extended the subject’s knee until the subject felt a very mild stretching sensation in his hamstring muscles. Then, the therapist asked the subject to flex his knee against the resistance applied by the therapist’s hand. The subject was asked to use a force around 50% of his maximal strength. No movement was allowed to occur in the knee joint so that an isometric form of contraction was gained in hamstring muscles. The subject holds the contraction for 8 seconds and then, on the command of the therapist relaxed the hamstrings muscle. Immediately after the muscle relaxation the therapist stretched the hamstring muscles up to a point where the subject reported a mild to moderate stretching sensation without any pain and hold this position for 30 seconds. The therapist repeated this procedure three times in every session.

In spite of many research studies performed on the issue of stretching, there are still disagreements about the most effective and safe method, intensity, duration and frequency of stretching(10, 13). Several studies have focused on comparing the different methods of stretching. Some of these studies have found that PNF stretching and static stretching were equally effective in improvement of muscle extensibility(7, 13-14). Others have shown that PNF is more effective than static stretching(9, 15). On the contrary, Davis et al reported that static stretching is more effective(16)
After signing a consent form, the subjects were randomly assigned to one of the three groups of static stretching, hold-relax PNF and control. At the beginning of the first session, the extensibility of hamstring was assessed for every participant. We used Active Knee
The treatments in both static stretching and PNF groups were applied for three sessions in one week with one day rest between two sessions. The treatments continued for two successive weeks, and thus every subject received 6 sessions of treatment during the study. At the end of the last session, the popliteal angle was measured again in the similar way as that of the first session.
The controversy around this issue was a motive for conducting the present study. One limitation of the previous studies, comparing the different techniques of stretching, was that the intervention was applied only for one Session. In this study, we aimed to compare the effectiveness of several sessions of static stretching and hold-relax PNF on increasing the extensibility of hamstring muscles.
After the initial measurement, the subjects in either of the two intervention groups (i.e. static stretching and PNF groups) received the treatments as following:
PNF group
Statistical analysis
Muscle, fascia, capsule and tendon are the primary limiting factors of joint movement. Therefore, it is necessary to consider the muscle spindle and Golgi tendon organ in the ability of muscles to lengthen in response to stretch, as well as the passive structures. PNF stretching techniques focus on active components and static stretching address the passive components which limit the range of motion(17)
The superiority of PNF technique on static stretching observed in our study may be due to the different effects of these techniques on the blood flow of muscles(11, 18). The resultant muscle relaxation following PNF techniques can cause changes in blood flow. PNF technique increase motor activity that can affect vascular function. The muscle activation may increase
The subjects in the control group received no treatment during a two weeks period. At the end of the second week, the therapist measured the popliteal angle similar to what he did for the other two groups.

Another explanation for the disagreement between this and the previous studies, could be that we performed the intervention techniques in several sessions, while, other studies used the techniques in only one session(7-8, 13, 15). Probably, the effects of the stretching techniques have been accumulated during the six sessions of our study. We may propose that, if there is a real difference between the two techniques of stretching, one session of treatment might not be enough in detecting that small difference. When the treatment effects are accumulated during several sessions, then, the difference between the two techniques get larger and hence statistically significant.
The mean age of the subjects and the mean angle of knee extension at the baseline of the study were compared by Kruskal-wallis and ANOVA tests (Table1). There were no significant differences between the three groups in this regard. At the end of the treatment period, we found a significant difference in the angle of knee extension among the study groups (Table2). A post hoc test using Mann-Whitney test with Bonferroni correction showed significant differences in pair wise comparisons of the study groups. Since there were three pairs of comparison, the alpha level was set on 0.0167 (á level =.05/3= .0167). The angle of knee extension was significantly larger in both treatment groups compared to the control group (p<0.001). Moreover, the subjects in PNF group showed significantly greater angle compared with the static-stretch group (p=0.015).

In static stretching, the inverse myotatic reflex results in muscle relaxation and further stretch and range of motion. In hold relax – PNF, the neural inhibition reduces reflex activity(13). An inhibitory interneuron reduces á-motoneuron activity of antagonist muscle(8) which results in muscle relaxation and decreased resistance to stretch(13).
Our study found that hold relax – PNF was more effective in increasing hamstring extensibility. The previous studies on this issue, have found no difference between these two methods of stretching (7) . The discrepancy between our study and the previous ones could be explained by several issues. The subjects on our study were relatively young (i.e. 18-30), compared to the Feland’s study which were on 55 to 79 years old people. Feland et al, has stated that PNF stretching in the younger patients is more effective than in older ones. This is due to the age-related neurophysiologic and musculoskeletal changes such as motor neuron death and increased collagen of the skeletal muscle, in older people(13). In the O’Hora’s study that was on 21 to 35 years old people, the results was similar to our study(15).
FINDINGS
Due to non-normal distributions of the study data, we used Kruskal-wallis test with Bonferroni correction to compare the hamstring extensibility among the three study groups.

the release of vasoactive substances which results in vascular dilation(18). On the other hand, the muscle extension due to static stretching decreases muscle blood flow(11, 19) because of two physical changes: 1) longitudinal extension of blood vessels with the muscle extension and 2) the increase of intramuscular pressure during the stretching(19). Hyperactivity or hyperemia can affects the muscular temperature(20). During the exercise, muscle temperature increase from 35 to 40 degrees due to elevation in plasma ATP. The increased temperature of collagen will increase tissue elasticity(21)

The objective was to determine the reliability and feasibility of Community Balance and Mobility Scale (CB&MS) as a screening instrument for identifying balance dysfunction in elderly population in an Indian situation. An observational study was conducted in community and old age homes residing elderly population, involving 33 elderly individuals aged 60 years and above, selected by convenience sampling method. CB&MS and Computerized Static Posturography measures were used for assessment. Intraclass Correlation Coefficient and spearman's correlation coefficient were used for analysis. Results showed high test-retest reliability (0.985) but no correlation with velocity moment measure of Computerized Static Posturography. Our findings demonstrated that CB&MS is reliable and feasible and hence could be applicable in the community for assessing balance and mobility of young old elderly population.

Although a number of procedures have been described to assess balance, many of these techniques present difficulty in application due to cost, subjectivity, specificity of assessment or other problems6. In spite of laboratory measures of balance offer greater precision and potential to detect subtle or sub clinical balance impairments, Clinical and Functional tests of balance (static and dynamic) share the advantages of ease of administration, low cost and more directly interpretable functionalComputerizedrelevance16.Posturography is the gold standard tool to evaluate postural sway and quantify balance.

Reliability and Feasibility of Community Balance and Mobility Scale (CB&MS) in Elderly Population
Ageing, in its broadest sense is the continuous and irreversible decline in the efficiency of various physiological processes2.The average life expectancy is around 60 years now and the way health care facilities are expanding with better income levels and access to medicare, the life expectancy may rise between 70 and 75 by 20208.India had the second largest number of elderly (60+) in the world.The size of India’s elderly population aged 60 and above is expected to increase from 77 million in 2001 to 179 million in 2031 and further to 301 million in 2051. The proportion is likely to reach 12 per cent in 2031 and 17 per cent in 2051 17

ABSTRACT
INTRODUCTION

Among community-dwelling older people over 64 years of age, 28-35% fall each year. Of those who are 70 years and older, approximately 32%-42% fall each year. Older people who are living in nursing homes fall more often than those who are living in the community. Approximately 30-50% of people living in long term care institutions fall each year, and 40% of them experienced recurrent falls 20 . Balance disturbances frequently cause elderly people to seek medical advice and admission to hospitals and residential homes3
A decline in all the major systems for example, cardiovascular, metabolic, respiratory, and neuromuscular contributes to weakness, fatigue, and slowing of movement that have been the hallmarks of aging14Older adults have impaired balance recovery due to an age-related decline in the ability to rapidly and efficiently contract the muscles of the lower extremities .These physiologic changes of normal aging may increase the risk of falls13.This led to increase in the number of older persons with disability9

An observational study with convenience sampling method was conducted at department of Physiotherapy, MCOAHS, Manipal, India. The sample size for the study was estimated from the previous existing study, consisted of 33 (20 males and 13 females) elderly persons aged above 60 years and were able to understand and follow commands. Subjects who had acute illness on the day of assessment, foot ulcers, acute labyrinthine disorders, functional hearing & visual deficits, cognitive impairments and non-cooperative participants were excluded from the study.
Postural sway amplitude and velocity
After measuring the height, weight and age, subjects were instructed to stand with normal base of support on the force platform of Posturography machine with arms folded in front of chest. Subjects were instructed to stand relaxed on force platform, bare foot, with the head in a straight head position. They were asked to focus on specific point (2 m distance) at their eye level during eyes open conditions and the timer is started. After 30 seconds, the timer is stopped and the subject is rested for two minutes.
Data analysis
An 8 meter track with duct tape was made which is of 5cm width on the floor with a perpendicular start line and finish line. Markings done at 1m, 2m, 4m and
The study protocol was presented and approval was obtained to conduct the study by the ethical committee of Manipal University. Elderly subjects in the age group of 60 years and above were identified from the community and old age homes after which they were screened for inclusion and exclusion criteria. The selected subjects were explained about the study and informed consent was obtained for their participation. The subjects were assessed for the following measures as explained below.

6m with a tape perpendicularly. A 40cm bare spot was placed for item 3 and 4 after 6m mark. The visual target for items 8 and 11 was placed at the 4m mark, at individual’s eye level and 1m from the outside edge of the track. Individuals were advised to wear comfortable clothes. All items (total 13) were scored in the first trail after explaining each one task and ensuring rest periods in between tasks as required.
The set up resembles as
The same procedure is repeated with subject standing with normal base- eye closed for 30 seconds, tandem stance –the heel of one foot touches great toe of other foot, the foot position according to convenience of patient (eyes open and eyes closed) and both right and left single leg stance while opposite leg flexed at knee for 20 seconds. Two minutes of rest was given in between each position. The subjects who did not stand for 30 seconds in normal stance eyes open and eyes closed and 20 seconds in remaining testing positions even after two trials, the test is stopped and noted down as unable to test. After all the testing positions were done, velocity moment noted down from the computer. These readings were used to correlate with CB&MS and Tinetti POMA balance subscale measures.
velocity of anterior-posterior and medial-lateral sway during standing in different positions are measured using Posturography. The general census is that computerized measures have a greater precision and potential to detect sub clinical balance impairments1
Data was analyzed using SPSS version 16.Test retest reliability of CB&MS was analyzed using Intraclass Correlation Coefficient. Concurrent validity of CB&MS with posturography measure (Velocity Moment) was
Role of Posturography in elderly population to detect balance impairments has gained importance in the recent years. However the balance measures were assessed in clinical set up where the elderly individual does not encounter barriers that challenge his balance abilities. This necessitates the assessment of balance in community environment.
PROCEDURE
MATERIAL AND METHOD
CB&MS is a tool used to measure balance and mobility of individual in the community setting. The scale has been used and found to be valid and reliable in high functioning patients with traumatic brain injury10. This scale has not been tested for its usefulness in Indian elderly population and no literature is available to correlate this scale with the postural sway measures of Posturography. Our study aims to find the reliability and feasibility of CB&MS and its correlation with postural sway measures using Static Posturography.
Initial evaluation using CB&MS was done and revaluation was done after a period of one week for determining the test –retest reliability.

healthy elders, subjects could not attain full score in CB&MS. A number of factors could have contributed to the decrease in successful performance and not attaining full score in CB&MS. First, the tasks were challenging as certain items are time scored, in which (item no I-right and left, VI, VIIright and left, IX,X,XI-right and left ,XIII-right and left) they have to complete the tasks within the time limit in order to attain full score. Second, the complexity of tasks which include hopping forward, crouch and walk, running with controlled stop, and lateral dodging which requires good strength ,balance and coordination. These observations were supported by earlier study done by Scott J.Butcher et al 2004 Although not tested in this study, the fact that women tend to have lower muscle strength than men15 could explain their lower performance on these items in the 60 to 72 year age category (table1). Slow speed of performance, particularly for item 7(lateral dodging), could also be attributed to slowness in reaction time with increasing age5. A decrease in speed has previously been attributed to age-related reduction in muscle fibre size, particularly in type II fibres, which are primarily responsible for speed of movement 20
In our phase results, we did not find any correlation between items of CB&MS and Posturography measures which could be explained by the difference in measurement surface, environment and nonfamiliarization of Posturography. Posturography measures were taken on force platform in well designed and organized laboratory setting as against to CB&MS which was performed in real setting.
it does not require any special equipment to be performed in the community setting. Uneven surfaces in community could be utilized since people would have accommodated to that specific environment. This also leads to evaluation in actual real life setting instead of clinical setting. All subjects completed the test without any adverse events and hence it is safe to be used in young old elderly population.
Our results were restricted to young-old elderly population and hence cannot be generalized to oldold. However, we would like to recommend further studies to test the feasibility of CB& MS in old-old subjects.
The average time taken to complete the test administration was approximately 30 minutes.This is more compared to other assessment measures in elderly which could be explained by the progressive difficulty in task items. Some of the items were scored based on duration, which requires the subject to complete the

minimum time of 45 seconds (SLS).Some items need to be performed four (Lateral dodging) or five (Step ups) times and walk for seven consecutive steps (tandem walking) which further increased the assessment time. Rest periods given in between tasks could also have increased the test duration.
Poor correlation between CB&MS and Posturography could also be attributed to the different components of balance being assessed by two tests, that is Posturography measures static balance while, CB&MS measures dynamic balance and mobility tasks.

Cerebellar ataxia indicates dysfunction of the cerebellum. Ataxia literally means ‘without order’. The term ataxia refers mainly to inaccuracy of movement towards a target, to rhythmic limb movements either during a sustained posture or when the patient attempts to reach a target, inability to perform smooth alternate movements and loss of coordination of muscle groups in multi joint movements.1
The muscles stabilizing lumbar spine form the core muscles. This muscular control is required around lumbar spine to maintain functional stability.7 Core stability is defined as the ability of the lumbopelvichip complex to prevent buckling of the vertebral column and return it to equilibrium following perturbation.8
Patients with degenerative cerebellar lesions show global impairment of balance with greater instability in anterior- posterior direction than medio- lateral directions.2, 3 important factor contributing to instability is decreased knee and ankle flexion when tested through perturbations 3. Individuals with cerebellar ataxia show more co-contraction modes of muscles resulting in stiffness of muscles of major joints e.g. knee stiffness and result in impaired coordination during feedback and feed forward postural control 4Studies reveal cerebellar gait ataxia is more related to balance deficits than voluntary leg coordination deficits.5

Core Stability Training with Conventional Balance Training Improves Dynamic Balance in Progressive Degenerative Cerebellar Ataxia
ABSTRACT
INTRODUCTION
Background and Purpose: Disorder of balance and gait is the commonest feature found in Cerebellar ataxia patients. Purpose was to see the effect of Core stability training along with balance training on dynamic balance in progressive degenerative Cerebellar Ataxia.
DATA ANALYSIS
Subjects with Progressive degenerative ataxia of cerebellar origin diagnosed by neurologist, age range from 18-50, MMSE score e” 24,Chronic cases having symptoms more than a year, SARA score 15-23, 20 Subjects should be able to walk minimum distance of 10 meters with or without walking aid were included in theSubjectsstudy.20diagnosed as Afferent/ sensory ataxia, any other neurological or orthopaedic disorder affecting gait or balance, severe Low back pain, Already undergoing

A sample of 20 subjects with progressive degenerative Cerebellar ataxia (18 subjects were SCA and 2 were olivopontocerebellar atrophy) participated in the study. Out of 20, 15 were male whereas 5 were female. 18 subjects suffered from SCA’s (type 1, 2, 3) and two from olivo-ponto cerebellar atrophy. A sample of convenience was taken.
superficial muscles for gaining spinal stability9,10,11. Core strengthening improves dynamic postural control in rehabilitation of athletic injury.12
The purpose of this study was to determine whether the addition of Core stability training to conventional balance training in patients with Progressive degenerative cerebellar ataxia has any benefit on dynamic balance as compared with conventional balance training alone. Dynamic balance is a problem in patients with Progressive Degenerative Cerebellar Ataxia. The trunk muscles form the basis of core which acts as the powerhouse for force production and coordinated limb movements during locomotion.13 Core Stability training it is aimed to create awareness of muscle contractions around the spine which have eventually weakened due to chronic nature of disease.2,3 Also in progressive degenerative Cerebellar Ataxia the synergies required for maintaining Dynamic Balance are altered.4 The synergies can be strengthened through training of Core muscles.14 If the study reveals positive effects of core stability training on dynamic balance, treatment protocols can be developed to improve dynamic balance with ease in every clinical setting.
The change in the Dynamic Balance and Fear of falls was measured at three levels of the treatment phases, initially at pre treatment, then post treatment and last at follow up
The data was analysed using SPSS software version 15. Independent T-test was used to see the difference between the effects training between group A and B.Effectiveness of treatment within the groups was measured using repeated measure ANOVA. The results were checked at P<0.05 level of significance.
Subjects in group A were treated with core stability training which included back stabilization exercises, single leg slides, leg loading, facilitation of Transversus abdominis, bridging, Pelvic floor exercises and diaphragmatic Breathing while balance training included turning, walking sideways, heel to toe walking, sit to stand, heel lifts, toe lifts, single leg standing ,leg swings, stair climbing. Subjects in Group B treated with balance training and relaxation training15, 16,17,18,19 at Institute of Human Behaviour and Allied Sciences Hospital, Delhi.

physiotherapy intervention for last 3 months, Uncorrectable visual or hearing loss, Subjects unwilling to follow the exercise regime were excluded. It was a prospective repeated measure experimental group design. Instrument used for exercise regime was pressure biofeedback device16, 21 (Chattanooga group). A duly signed consent form was obtained from the subjects. A detailed assessment of every subject was done using neurological evaluation form. All the subjects were assessed for inclusion and exclusion criteria. The mini mental status examination was done. Demographic data of the subjects were collected. Subjects were assigned systematically into two groups – group A experimental and group B conventional treatment groups.
The treatment sessions for both the groups were given for 1 hour per day, 3 times per week for 4 weeks The performance of the two groups was examined on the following scales: Dynamic Balance was tested on Balance Evaluation System Test(BESTest)22 and for fear of Falls Modified Falls efficacy scale (MFES) 23was used..The outcomes were taken 3 times during treatment first before treatment, second immediately after the 4 weeks of treatment and third after a month’s follow up. The treatment was given n the physiotherapy department of the IHBAS hospital. The study was reviewed by the ethical board of Jamia Hamdard University, New Delhi.
RESULTS
The Mean ± SD values for BESTest in experimental group after 1 month of treatment was 63.50 ± 15.757 and conventional group was 50.00 ± 11.981.This difference in values was statistically significant p=0.045. The Mean ± SD values for experimental group from pre intervention to Follow Up was 55.60 ± 17.602 the result was statistically significant (P=0.024) and conventional group was 40.10 ± 9.327.This difference in values was statistically significant (p=0.024), indicating that the

The results found this study are supported by the work of Paul W. Hodges which provided the rationale of core stability training, that stability of spine depends on both the muscle activation and CNS control.14 The core stability training results in motor learning sequentially through skill learning, precision training, activation in variety of contexts, integration of skills

The rationale behind the fact that patients did not return to pre treatment level or their condition did not decline due to progression of disease, is that the natural progression of degeneration in Cerebellar ataxia is 0.62.5 points 1 year as found on SARA scale depending on genotypes (data of EUROSCA natural history. Thomas Klockgether, 2008).5 Long term effects of intensive exercise training have been proven in research on progressive degenerative cerebellar disease even after a year of training.29
results obtained may be attributed to the 1) gender differences, in experimental group there were 3 females and conventional group there were 2 females, because the females were seen to have less confidence than males of same severity.23, 30 2) Considering age differences, in conventional group 3 patients were of age 45years and above, while in experimental there were 4 patients having age 45years and above. 3) Considering

Liebenson found trunk stabilization exercises resulted in reduction of low back pain, by increasing the kinaesthetic awareness necessary to maintain safe neutral spine which is ideal for rehabilitation.24 Nicole L et al. studied on dynamic balance testing among young healthy adults and found that core strengthening improves dynamic postural control during rehabilitation of athletic injury.12 The diaphragm serves as the roof of the core; stability is augmented on the lumbar spine by contraction of diaphragm and increasing intraabdominal pressure. 13 Pelvic floor musculature is co activated with the Transversus abdominis contraction.13

There was no statistical significance in improvement of the falls score at post treatment (p=0.433) and at follow up (p=0.154).However experimental group showed clinical improvement in falls score. When baselines (fig.1.2) were compared for both the groups it can be observed that the difference for improvement was more in Experimental group than the conventional group.The
the pressure biofeedback was used for core training including abdominal hollowing a basic exercise taught initially and then hollowing associated with lower limb movements. It activated Transversus Abdominis (TrA) muscle, which is important muscle forming core.26 It is found that the patient with cerebellar ataxia uses restricted synergies i.e. stiffening of pelvis, knees, and ankles during challenging tasks.27 It has also been found that practice could lead to transition from co-contraction to reciprocal patterns on the basis of uncontrolled manifold (UCM) hypothesis.28 This study included patients with chronic progressive disease, as above study mentioned that these patients use restricted synergies to maintain balance. Practice of core training along with lower limb activities provided in this study might have helped patients to develop reciprocal muscle pattern rather than the stiffening of the joints.28 resulting in reduction of synergies and their strengthening which are essential for dynamic balance control.28

DISCUSSION
experimental group showed more improvement in Balance than the conventional group. Although there was no statistically significant improvement in the scores at post treatment (p=0.433) and at follow up (p=0.154) after treatment.
Table 1.2 Comparison between pre, post and follow up scores of experimental and conventional groups on MFE
The key findings that emerged from the study were that core stability training is effective in improving Dynamic balance in progressive degenerative cerebellar ataxia. Core stability training group showed significant improvement on BESTest till follow up compared to conventional balance training group. There was no statistical difference found in the MFEscale among the two groups but the results were clinically significant at follow up for core stability training group.
The results obtained show that the core stability training improves dynamic balance. However it was seen that although there was clinical improvement of scores on MFEScale, but no statistical significance was observed. Thus it is concluded that in rehabilitation of dynamic balance in patients with progressive Cerebellar ataxia, core stabilization programme can be included as an adjunct to conventional balance training.

disease severity, in conventional group 4 subjects were above 16 scoring of SARA scale, while in experimental there were 5 subjects scoring more than 16. The above factors may be the possible causes of difference of MFEs score at pre treatment level that led to no statistical significance even though the experimental group improved more than conventional group.

ABSTRACT
Conclusion: Adding muscle energy techniques to the treatment of adhesive capsulitis gives better outcomes compared to treating with joint mobilization alone.
Background: The glenohumeral hypomobility in adhesive capsulitis causes excessive scapular motion to compensate for the reduced gleno-humeral motion. The resulting tightness of upper trapezius and levator scapula causes an altered scapular position at rest. Restoring normal length of upper trapezius and levator scapulae will help to restore an optimal length-tension relationship and scapular position resulting in better improvement of glenohumeral range of motion.
Research supports the view that patients suffering from frozen shoulder syndrome compensate for

Restoration of Normal Length of Upper Trapezius and Levator Scapulae in Subjects with Adhesive Capsulitis
Study Design: Prospective clinical trial of subjects with Adhesive Capsulitis
Methods and measures: 60 male subjects with unilateral adhesive capsulitis were divided into group I and group II of 30 each. Baseline outcome measures assessed were shoulder ROM of flexion, abduction and external rotation and resting position of the scapula using the Lennie test. Group I received Muscle Energy Technique (MET) for upper trapezius and levator scapula along with Maitland joint mobilization for the glenohumeral joint. Group II received Maitland mobilization for the gleno-humeral joint. Outcomes were reassessed at 6 weeks.
The impairments are pain and loss of active and passive mobility of the glenohumeral joint. Abnormal scapular motion, such as excess elevation and increased outward rotation of the scapula during elevation of the arm, is generally thought to be a compensation strategy for a limited glenohumeral motion, muscle imbalance and pain 3. In a trial of ten patients with unilateral frozen shoulder syndrome for 3 months early scapular lateral rotation of the frozen shoulder during elevation of the arm using an electromagnetic tracking device was documented 5
INTRODUCTION
Adhesive capsulitis is a condition causing painful and restricted motion of the glenohumeral joint. Normally the entire glenohumeral joint in the resting position (arm dependent at the side) is surrounded by a large, loose capsule that is taut superiorly and slack anteriorly and inferiorly (redundant folds or axillary pouch) 1. Hyaluronic acid with water is the lubricant between the collagen fibres that allows the free gliding to occur 2.The pathogenesis of adhesive capsulitis involves the entire capsule with more involvement of the antero-inferior axillary folds which are shrunken and fibrosed 3,4

The following outcome measures were assessed on day 1 and at the end of 6 weeks (18th treatment session).
•Prospective clinical trial of 60 male subjects with adhesive capsulitis from the outpatient department of physiotherapy at Seth G.S. Medical college & K.E.M. hospital Mumbai.
We begin with the null hypothesis that there is no relation between combining muscle energy techniques for upper trapezius and levator scapula and Maitland joint mobilizations for glenohumeral joint as compared to treating glenohumeral joint alone with Maitland joint mobilization.

impaired glenohumeral motion via the use of accessory musculature i.e. increased trapezius muscle activity 6 The upper trapezius and levator scapulae are considered to be postural muscles and hence undergo shortening in response to stress or overuse 7 . The scapula on the involved side is usually elevated, laterally rotated and abducted 2. Studies on treatment of adhesive capsulitis concentrate on treating glenohumeral joint. But little attention is paid to normalize scapular static and dynamic mechanics which are essential for normal glenohumeral rhythm. Hence the focus of this study was to find the effect of restoration of length of the shortened upper trapezius and levator scapula muscle with muscle energy technique and sustained passive stretching techniques along with Maitland joint mobilization for glenohumeral joint as compared to Maitland joint mobilization alone on pain scores, range of motion and scapular position at rest in subjects with unilateral adhesive capsulitis.

The underlying basis for the use of hot packs is the ability of heat to elevate pain threshold, alter nerve conduction velocity and change in muscle spindle firing rate
Both the groups showed a significant improvement shoulder range of motion. Intergroup comparison indicates that group I showed significant improvement post treatment at the end of 6 weeks (18th session) on the above mentioned outcome when compared to group II. However, the improvement of scapular position post treatment was seen only in group I
the null hypothesis was rejected and the experimental hypothesis was proved.
The primary role of mobilization is to restore joint play and facilitate joint movement by restoring arthrokinematics. The neurophysiologic effect is based on the stimulation of the peripheral mechanoreceptors and inhibition of nociceptors The biomechanical effect is based on breaking up adhesions in the capsule, collagen fibre realignment and improving interfibre glide 2. A multiple-subject case report concluded that there seems to be a role for intensive mobilization techniques in the treatment of adhesive capsulitis 13. Hence there was increase in ROM of the shoulder over a period of 6 weeks.

Scapular position improvement was seen secondary to the treatment of the upper trapezius and levator scapula muscle using muscle energy technique could be attributed to the therapeutic effects of muscle energy techniques. Many authors have proposed that MET techniques facilitate stretching by producing neurological reflex muscle relaxation 7 following isometric muscle contractions mediated by Golgi tendon organs. Connective tissue elongation is time dependent, and if a constant stretching force is loaded on the tissue, the tissue will respond with slow elongation or creep causing greater deformation i.e. there is viscoelastic or muscle property change 7 Myofascial structures have two distinct connective tissue arrangements: elastic ‘parallel’ fibres, arranged parallel to the muscle fibres, and the stiffer ‘in series’ fibres that lie perpendicular to muscle fibres and found mainly at the tendinous junctions. Passive stretching would elongate the parallel fibres but have little effect on the ‘in series’ fibres; however, the addition of an isometric contraction would place loading on these fibres to produce viscoelastic or plastic change above and beyond that achieved by passive stretching alone. Literature suggests that MET methods produce a greater change in stretch tolerance 7 than passive stretching by decreasing an individual’s perception of muscle pain.

Shoulder ROM of external rotation showed extremely statistically significant improvement within both the groups post treatment (p < 0.05). In inter- group comparison, group I showed more highly statistically significant improvement in external rotation as compared to group II (p < 0.05).

Stretching and isometric contraction stimulate joint muscle and joint mechanoreceptors and proprioceptors, and it is possible that this may attenuate the sensation of pain.The
CONCLUSION
Restoring length of upper trapezius and levator scapula is essential when treating patients with adhesive capsulitis. While assessing patients with adhesive capsulitis attention needs to be given to assessment of abnormal scapular position. Treatment

above mentioned mechanisms contributed to reduce over activity and increased length of the upper trapezius and levator scapula muscle. This was reflected on the scapular position in Group I on the Lennie test. Literature supports the view that abnormal compensatory scapular movements in patients with shoulder stiffness can be reduced. In a particular study, it was demonstrated that with simple motor control instruction, the subjects reduced the amount of scapular elevation and retained relative timing and control 12.

Materials & Method: SUBJECTS; 25 diagnosed with PFPS and 25 asymptomatic control were recruited for study. EMG activity of VMO VL was recorded by surface electrodes.EMG data were analyzed in three activities for both groups, ISOMETRIC, CONCENTRIC and ECCENTRIC exercise. Outcome measure was EMG MUAP amplitude and Q-angle.
In one study done by Winslow et al 1995 out of 16,748 patients presenting with sports related musculoskeletal problems, 11.3% had an anterior knee pain. Incidence of PFPS in general population is reported in some studies to be high as one in four with proportion increase in athletes. (Levine 1979, Outbridge 1984)
rate is 20% in students in USA and morbidity is directly proportional to activity of Patients [3]
natural history of PFPS report that in general it is a benign condition that may improve or persist over time serious disability is uncommon. PFPS is a condition of both malalignment and muscular dysfunction.Rehabilitation exercises can restore PF joint homeostasis although the anatomical malalignment of PFPS may not be corrected. [5]
Female patient are particularly more affected than male [2]. Incidence rate is 7% and 10% in young male and female.
Conclusion: There was significant difference in VMO/VL ratio and Q-angle in both groups.

Twenty five subjects diagnosed with PFPS on the basis of clinical examination and referred from orthopedic OPD, and 25 asymptomatic controls were recruited for the study. Subjects were selected on the basis of inclusion and exclusion criteria. Detailed assessment of patients with diagnostic tests for PFPS and radiological examination was done. All subjects were provided written informed consent. Then patient’s data was entered to EMG programme (Neuro Perfect plus Software) in computer. Then EMG surface electrodes with gel were placed over the selected muscle. Micropore tape was used to adhere the electrodes on skin.EMG
VMO placed over the muscle belly approximately 4 cm superior to and 3 cm medial to the superomedial patellar border and oriented 55 degrees to vertical. [19] (FigEMG2)
Dynamic Q-angle was measured for both groups. For static Q-angle measured with knee in full extension with subject in supine position. ASIS (anterior superior iliac spine), centre of patella and tibial tuberosity was marked with pencil. The angle formed by the intersection of line from ASIS to centre of patella with centre of patella to tibial tuberosity was measured in degrees with universal goniometer. [Fig-3]

A Study to Check Added effects of Electrical Stimulation with Task Oriented Training in Hand Rehabilitation among Stroke Patients
INTRODUCTION
stimulation of spastic wrist flexor muscles was compared with passive stretch of wrist flexor by king who reported a significantly greater effect of electrical stimulation on flexor spasticity.6 However alfier10 stated that “no direct stimulus must be allowed to reach spastic muscle” and he reported a reduction in flexor spasticity after electrical stimulation of extensor muscles.Electrical
Findings: statistical significant difference found for all the variables used in methods in between the groups.
Methods: 30 subjects were selectively divided in to two groups. Group A received Eletrical stimulation with Task oriented training while Group B received only task oriented training. Outcome measures were grip strength, Box and Block test, 9 hole peg and ROM.

Stroke is an acute onset of neurological dysfunction due to an abnormality in cerebral circulation with resultant sign and symptoms that correspond to involvement of focal areas of the brain. The term cerebrovascular accidents (CVA) are used interchangeably with stroke to refer to the cerebrovascular conditions that accompany either ischemic or hemorrhagic lesions. To be classified as stroke, focal neurological deficits must persist for at least 24 hours.
is the third leading cause of death in industrialized countries and the leading cause of adult disability. Half of all stroke survivors are left with major functional problems in their hands and arms.2
ABSTRACT
Electrical5
Objective: To determine the added effects of electrical stimulation combined with task oriented training in stroke patients.
Conclusion: Electrical stimulation with task oriented training improves hand functions more effectively compared to only task oriented training in stroke patients.
Although initial neurological loss in arm is generally thought to be predictive factor for overall recovery it has been reported that the recovery of the upper extremity function is independent of the overall level of stroke severity. 3

that repetitive active movement, mediated by neuromuscular stimulation can enhance motor relearning after CNS damage. The additional component of movement provides augmented sensory feedback and propioceptive afferent stimulation. There is reorganization of cortical representations for body parts basal upon the afferent input that they contribute as well as the amount of motor activation they undergo. With electrical stimulation there is evidence that it equally influence this reorganization. This can be highly advantageous in limbs that are impaired to such a degree that a voluntary movement could be impossible. Because of significant amount of hemiparesis that is caused by stroke, the use of electrical stimulation to generate movement provides the means of inducing positive motor changes associated with motion.16

has been applied as a therapy in humans with central nervous system (CNS) injuries although there is no conclusive direction as to which technique works the best for a given indication. There are convincing studies available to show that electrical stimulation can strengthen atrophied muscles, change in muscles property, increase the muscle bulk, and improve the circulation and the change in the metabolism.10Thereisevidence
Cauraugh14 et al focused on less severely affected subjects, like those in the present trial spasticity were not assessed; they reported improvement in sustained contraction of wrist extensor muscles and in function (box and block test) but no effect on motor control. From the publication, it is not clearly whether there was no gain in motor control or no difference in gain. In a letter trail function improvement was confirmed but the clinical relevance of this improvement was not discussed. In this study it seems that functional improvement can be clinically relevant for subjects.

CONCLUSION
Both electrical stimulation along with task oriented training and only task oriented training were useful to improve hand functions.
in such a way that patient had ample opportunity to gain this experience. First the patients were involved in identifying their own problems in performance. These problems are called the missing performance component. The selection of task used for training was meant to target those missing performance components training in the functional tasks followed through on the same missing components. The incorporation of this strategy turned the programme into a client centered intervention. The training thus become more anticipatory for the patients and hence was more selfinitiated, targeted and effective.15 Limitation of the study was absence of control group; neither patients nor the therapist were blinded.

Background: People with stroke are at risk of falls. The majorities of individual with stroke has some degree of residual impairment, but regain walking ability and will be discharged home. Three quarters fell in the first six month after their discharge from hospital. Identify increased knowledge of incremental risk factors for falling and the assumption that some of the identified risk factors can be modified may lead to development of intervention to reduce number of falls
Patients with stroke have up to a 4 fold increased risk of hip facture because of their high incidence of falls.12 It has been shown that stroke patients in addition have reduced bone mass in their paretic extremities, that this development of hemi osteoporosis is extensive and pronounced, and that begins early after stroke onset.13Furthermore,

Stroke is an acute onset of neurological dysfunction due to an abnormality in cerebral circulation with resultant sign and symptoms that correspond to involvement of focal areas of the brain. The term cerebrovascular accidents (CVA) are used interchangeably with stroke to refer to the cerebrovascular conditions that accompany either ischemic or hemorrhagic lesions.1 Stroke is the most common cause of chronic disability.2 People with stroke are at risk of falls.3,4 The majority of individuals with stroke will have some degree of residual impairment, but will regain walking ability and will be discharged home following hospitalization. Although impairment is common, most people with stroke will regain walking ability; however poor balance and impaired gait can persist.
Objective: To explore the relationship between cognition, mobility and functional performance with respect to fall incidence in recovering stroke patients.
Conclusion: Cognition, mobility and functional performance might contribute to fall risk and fall related injuries in recovering stroke patients.

that 37% stroke survivors reported at least one fall during the first six months after their stroke. Among whom those fell, 37 percent suffered an injury that require medical treatment, and 8 percent suffered a fracture. Among those who fell, about half fell only once, but 12 percent fell more than five times. The study also found that 77 percent of patients fell at home.31Study

has been found that most of the falls occurred in home during walking activities.
DISCUSSION
It has been hypothesized that MMSE, POMA and Barthel Index score would be associated with fall incidence and be a risk factor for falls in recovering stroke patients, and result supported the hypothesis.
Table 2. Variable analysis
Table 3. Characteristics of subjects participated in the study
Further recommendation
age as a risk factor for fall, studies showed that fall incidence rate is much lower in older community dwelling adults without stroke (11%-30%) than rates for people with subacute stroke (25%) 4. Reason behind that is pathophysiology of stroke that changes the mental state dramatically.2
LIMITATIONS
MMSE, POMA and Barthel index are able to explain the fall incidence in recovering stroke patients. There is a significant relationship between cognition, mobility and functional performance to fall incidence. Cognition, Mobility and functional performance are some of the factors responsible for falls in recovering stroke patients, and might contribute to fall and fall related injuries.

The clinical information (cognition, mobility and functional status) collected at the time of discharge may have been different at the time of fall. But the study outcome gave the predictive information about the future fall incidence (i.e. six month) with these measures.During the 20 weeks time frame used for fall history, participants could have experienced on illness (e.g. flu, cold) or an exacerbation or worsening of an existing condition (e.g. arthritis, dementia) that could have negatively influenced their functional status at the time of fall(s). In contrast, participants might have been in worse physical or mental condition at the time of examination that at the time of the fall(s).
With increasing age the cognition, functional status and mobility level tend to decline, however stroke can worsen the mental status dramatically. Factors such as vestibular function, sensation, perception and home environment have not been assessed in this population in relation to fall risk.

3.Correlation of the variables studied can be done in stroke subjects with and without physiotherapy interventions.
MMSE, POMA I and Barthel Index are easily applicable tools and can be applied within minutes. Patients with relative low scores can be advised to be careful or to take further inpatient rehabilitation. Hip protectors can be given to the patients in order to avoid the fall related injuries.
The scales which have been used for the study are easily applicable to the patients within short time span, having good reliability33-35 and found useful tool to identify the subject who has more chances to fall following hospitalization in this study. However cognition, mobility and functional performance are not the only factors responsible for fall incidence, other factors needed to be rule out.

Background & Objectives: In assessment of spasticity in the pediatric population, methods used in practice are ordinal scales that lack reliability. Being a recent scale, Modified Modified Ashworth Scale has not been used in pediatric population as yet. This study aimed to assess inter- and intra-rater reliability of MMAS in assessing children with spastic cerebral palsy and also compare results with those of AS and MAS.
Methods & Materials: The study included 40 children with spastic CP with mean age 7.75 yrs .Functional levels of children were classified according to the Gross Motor Function Classification System. Spasticity in wrist, elbow and knee flexors was assessed according to the AS, MAS, and MMAS.
Conclusions & Interpretations: The MMAS is a reliable tool in assessing children with spastic CP and so are AS and MAS.
Cerebral Palsy is defined as a non-progressive group of disorders of movement and posture due to a defect or lesion of the immature brain.1 It can be further defined as a group of disorders of development of movement, posture and coordination with varied etiological associations and much phenotypic differences in the clinical presentation.2 Of the many types and subtypes of CP, none of them has a known medical cure and treatment is mainly symptomatic .3,4 One of the major manifestations of a sufficient intra-partum compromise of fetal cerebral perfusion include abnormal tone. However a study on the Indian population concluded that spastic quadriplegia constituted the predominant group ( 61%), followed by spastic diplegia (22%).5, 6, 7 Spasticity may be defined as velocity-dependent increase in muscle tone with exaggerated stretch reflexes.8,9 The nature of spasticity has prompted in a

range of assessment and management techniques. Different methods of spasticity assessment include electrophysiological tests, electromyography, dynamic flex meter, myometer, plasticity measurement system, and pendulum test and is kinetic dynamometer. However, they have limited clinical use. Methods most commonly used in clinical practice are the Ashworth Scale, the Modified Ashworth Scale, the Tardieu Scale and the Modified Tardieu Scale.10 When using clinical measures to assess spasticity, one assesses the resistance to imposed passive movement when the limb is briskly stretched through the full range of available movement about a joint.10 The Ashworth scale was created in the mid-1960s by Dr Bryan Ashworth as a way of judging the effectiveness of anti-spastic drugs.11 It is a 5-point ordinal scale and has been used extensively since then to assess increase in muscle tone in a range of neurological disorders. The Modified Ashworth Scale was created in 1987 by Bohannon and Smith who introduced a 1+ grade to increase the sensitivity of the original scale thus making it a 6-point nominal scale.12 With the MAS grades of ’1’, ’1+’ and ’2’ having been questioned as hierarchical levels of spasticity, recently the Modified Modified Ashworth

ABSTRACT
performed in a quiet environment . Subjects wore loose and comfortable clothing which did not pose any hindrance to the passive movements. Testing commenced five minutes after the subjects had been positioned. One repetition was done per joint. The scores for AS, MAS and MMAS were determined according to the level of resistance during the passive movement of the antagonistic muscles. The muscle groups tested were wrist flexors, elbow flexors, and knee flexors in the same order. Each test movement was performed over a duration of 1 second ( by counting “one thousand one”). A separate recording sheet was used for each session of each subject. As passive stretching is considered to affect the measurement results, measurements were repeated once on two different days of the study. To minimize the disadvantage of stretching of the spastic muscle, fast stretching was avoided. The data obtained was later statistical analyzed using the SPSS software.

Scale (MMAS) was created where grade ‘1+’ was omitted and the grade ‘2’ redefined in the MAS.13 Valid and reliable assessment tools are a pre-requisite in establishing baseline functions and monitoring developmental gains and also to contributing to an increasing body of evidence-based recommendations for CP. 14 Reliability of AS and MAS have been found to be poor to good as assessed in patients with various conditions.15,16, 17 18, 19 with values of MAS being slightly higher. The existing data suggests that the reliability of MMAS in patients with lower-limb muscle spasticity is very good, and it can be used as a measure of spasticity over time.20 21 . Although there are studies that conclude both AS and MAS are not reliable for the assessment of muscle spasticity, however experience and training may improve agreement between the raters.22,23,24 There is a need to standardize methods to apply these scales in clinical practice and research.25, 26, 27 Being a recent scale, the Modified Modified Ashworth Scale has not been used in the pediatric population as yet. It provides clearly defined and distinct grades to rate spasticity. Also, the other two scales i.e. AS and MAS give arguable results over their reliabilities in the same population. The present study aims to assess and the inter- and intra-rater reliability of the MMAS in three different muscle groups i.e. the wrist flexors, elbow flexors and knee flexors of children with spastic CP and also compare the results with those of the AS and the MAS which have already been used in the population under consideration.

Subjects with spastic cerebral palsy belonging to age group 4 to 14 years were recruited from Special schools in Delhi and NCR whose informed consent had been attained. All subjects with history of any orthopedic surgery , botulinum toxin injection or those on oral or intrathecal myorelaxant drugs , mentally retarded were excluded. The procedure was explained to the subjects and their parents. The functional level of participants was classified according to the expanded and revised Gross Motor Function Classification System ( GMFCSE & R ). Each subject was assessed by two raters in two different sessions randomly . Both the raters are physical therapists who are well-versed with the procedure of the assessment and blinded to the results of each other. For the inter-rater reliability component of the study, a 30-minute interval period is added between the assessments. For the intrarater reliability component of the study, one of the raters repeated the procedure the next day. The measurements were

and 2 in level V. MMAS shows moderate interrater reliability in level II for wrist flexors, and moderate interand intra-rater reliability in level III for knee flexors. Reliability of MMAS in levels I and II for all the muscle groups under study was good. It could not be assessed in groups IV and V owing to very small sample size. Hence future studies should assess the reliability with a large sample size of at least 40 in each level. The degree of training and preparation to use the scales probably exceeds the preparation of most clinicians using the scales.

CONCLUSION
reliability. AS is found to be moderately reliable with MAS and MMAS highly reliable in the knee flexors for lower limbs. Various factors may affect the measurement results of reliability. While investigating the reliability of scales, related joints, anatomical and biomechanical characteristics of muscle groups as well as interrater and intrarater change and biological change should be taken into consideration. Low reliability results of ordinal scales are related to problems which occur during the measurement of spasticity as well as the environment and general condition of the patient. To minimize this, the measurements were performed in a quiet environment and screened from other patients and therapists and one repetition was performed per joint. The error with repeated measurements taken on different days would be probably due to systematic changes in the participant status leading to change in the tone. However, we considered it was important to document test-retest variability of repeated measurements by inclusion of an intervening time period because in clinical practice, results from repeated measurements are rarely compared without an intervening time interval. This interval has contributed to an underestimation of intrarater reliability scores in this study because fluctuations of tone during a single day as well are well established. For this, grading on the second day was done at the same time of the day as on the first day. 24 Tone is not static and may change with time,17 this factor may contribute to low agreement between the raters. It is therefore essential that repeated movements are kept to a minimum.25 It is not surprising that the interrater reliability is higher than the intrarater reliability indicating that these scales should be interpreted with caution and even the same rater has possibility of making an error. One possible reason could be the clinical environment in the hospital. 26 Findings of this study are consistent with the previous studies showing very good inter- and intra-rater reliability scores in elbow flexors for all the three scales AS, MAS, and MMAS; scores for MMAS being the highest. The current study does not observe any association between the limbs, upper or lower, as well. This is probably due to the fact that only one muscle group i. e. knee flexors were investigated in the present study. Future studies should include more muscle groups to investigate the effect of limb, upper or lower, on the reliability scores. The results of the present study are little variant from the previous studies due to the age of the population included .Younger kids would be easier to move due to smaller limbs but would be harder to test due to reasons of adherence. Out of a total of 40, 10 subjects were in GMFCS level I, 14 in level II, 9 in level III, 5 in level IV,

Voluntary Ventilation (MVV) maneuver was conducted in following order:
Subjects were instructed to breathe normally through the mouthpiece. After the three normal breaths, they were asked to take deep inspiration followed by forceful expiration. And again they were asked to take three normal breaths without removing the mouthpiece. Parameters recorded in this manoeuvre were Tidal volume (TV) in litres, Expiratory reserve volume (ERV) in litres, Inspiratory reserve volume (IRV) in litres, Inspiratory capacity (IC) in litres, Vital capacity (VC) in litres.The

and weight were entered in the spirometer. The procedures of all maneuvers were demonstrated to the subject using disposable mouthpiece.
The Slow Vital Capacity (SVC) maneuver was conducted in the following order:
The study protocol was approved by the Institutional Ethics Committee. Patients were selected from those admitted to Surgery and Gynaecology ward of the Sassoon General hospital. 28 males and 22 females of the age group 30-60 years undergoing planned laparotomy were selected for the study. The study protocol was explained in detail to the selected patients. All the patients willing to participate in the study were asked to fill an informed consent form. Pulmonary function parameters were recorded preoperatively on one day prior to surgery and the postoperative readings were taken on fifth post-operative day. The PFTs were measured using a computerized portable RMS Helios 702(Chandigarh) spirometer (Photograph 1). This spirometer is automated and has a flow sensor which converts the airflow signals to digital signals. Values obtained were in litres and they were compared with the existing database for the normal healthy Indian population depending on age, sex, height and weight. Patients with history of cardiorespiratory diseases, diabetes mellitus or hypertension were excluded from the study. Also patients who had intra-operative complications, post-operative pulmonary, cardiac or surgical complications were excluded.Thetests were conducted according to the American Thoracic Society/ European Respiratory Society (ATS/ ERS) task force guidelines. The pulmonary functions were recorded in the sitting position and before the subject had lunch. The subjects were instructed to wear loose clothes on the day of test. Name, age, sex, height
Subjects were instructed to take slow and deep inspiration. Then subjects were instructed to hold the mouthpiece in the mouth with lips pursed around it and asked to blow forcefully into the mouthpiece as long as possible without hesitation and coughing. Then without removing the mouthpiece from the mouth, they were instructed to inspire maximally through the mouthpiece. Parameters recorded in this maneuver were Forced vital capacity (FVC) in litres, Force expiratory volume in one second (FEV1) in litres, FEV1/ FVC in %, Peak expiratory flow rate (PEFR) in litre per second and Peak inspiratory flow rate (PIFR) in litre perThesecond.Maximum

complications. In order to indentify the high risk patients we also studied the effect of gender difference (Male, Female), site of surgery (Upper abdomen, Lower abdomen) and BMI (Obese, Non obese) on postoperative PFT parameters.
1)To record various pulmonary function parameters (TV, ERV, IRV, VC, IC, MVV FVC, FEV1, FEV1/FVC, PEFR and PIFR) preoperatively and postoperatively in patients undergoing laparotomy.
We found that post-operatively there is decrease in TV by 21.87%, ERV by 22.01%, IRV by 23.64%, IC by 26.23%, VC by 25.54%, MVV by 26.28%, FVC by 26.32%, FEV1 by 28.97%, FEV1/FVC by 3.48%, PEFR by 32.31% and PIFR by 41.73%. All these differences were statistically significant except that in FEV1/FVC. (Table 1, Figure 1)

Adaptation of shallow breathing pattern without periodic deep breathing in post-operative period results in decreased surfactant secretion by type II alveolar epithelial cells. This decrease in surfactant secretion causes post-operative atelectasis, thus decreasing PFT values.[8]Ithas
been proved that there is dysfunction of intercostal muscles in post-operative period. Intercostal muscles play an important role in forceful respiration. So their dysfunction results in decrease in PFT values.[8] The situation is further aggravated by certain

To the best of our knowledge no one has studied all the PFT parameters as a whole in postoperative period as we did. Few authors have studied some parameters in laparotomy patients. Beecher HK [2] found a greater decrease in TV, ERV, IRV and VC as compare to our study. This may be due to the fact that their study measured PFT parameters on 2nd postoperative day while ours was on 5th postoperative day. Similar study conducted by Collins et al [3] on FVC, FEV1, FEV1/FVC and PEFR showed lower decrease in PFT parameters this may be due to they have studied it on 7 th postoperative day. Very few authors have studied effect of laparotomy on PIFR.

Patients undergoing upper abdominal surgery are more affected than that of lower abdominal surgeries
definitely reduce mortality and morbidity after laparotomy and will give very good results to surgeon who had used good surgical technique and alert mind for betterment of his patients.
CONCLUSION
post-operative factors such as prolonged recumbency, supine position and tight dressing over abdomen.[9]
Since these postoperative pulmonary changes can be easily diagnosed by spirometer, all patients undergoing laparotomy should undergo preoperative and postoperative spirometry. Also prophylactic preoperative physiotherapy and postoperative interventions such as deep breathing exercises, incentive spirometry and chest physiotherapy should be advised to all patients undergoing laparotomy. These simple and inexpensive procedures can make a significant difference in patients outcome after laparotomy.Thiswill
Furthermore, upper abdominal surgeries cause predominantly rib cage breathing in post-operative period, as shown by an increase in the ratio of oesophageal to gastric pressure swings (ÄPoes/ÄPga) and by decrease in the abdominal to rib cage excursions. This indicates that the intercostal inspiratory muscles are more active after upper abdominal surgery. [12,14] This is because the diaphragm is the muscle that is mainly affected during upper abdominal surgery. The mechanism that underlies the reduction in diaphragmatic strength and the shift to predominantly rib cage breathing is not fully understood, but anaesthesia and pain are definitely responsible for this dysfunction, some studies in animals and humans also showed that an inhibitory reflex generated during the
surgical procedure is the major mechanism. Manipulation of the splanchnic organs during laparotomy causes reflex inhibition of the phrenic nerve output decreasing diaphragmatic function. [15]
This can be explained by the fact that the diaphragmatic weakness is the main cause of postoperative pulmonary dysfunction and this diaphragmatic dysfunction mainly depends upon proximity of operative site to diaphragm. The proximity of operative site is inversely related to diaphragmatic function. This finding has been supported by the decrease in maximum inspiratory pressure, transdiaphragmatic pressure and expiratory muscle pressure observed after upper abdominal surgery in several studies. [ 12 13,14,15] This decrease is sustained for 48 hours after surgery and may persist for a week. [16,17]
2)Progesteron, the female sex hormone, has its own influence on chemoreceptor cells in medulla. Progesterone increases sensitivity of respiratory center to CO2. So whenever there are postoperative ventilation abnormalities in females, it causes stimulation of respiratory center due to progesterone and this may improve postoperative pulmonary function in them.[11]
We found after laparotomy in postoperative period, there are restrictive type of ventilatory changes. All these postoperative PFT decrease are more in male patients, in patients undergoing upper abdominal surgeries and in obese patients.
174 Indian Journal of Physiotherapy & Occupational Therapy. January-March 2013, Vol. 7, No. 1
Thus upper abdominal operations are associated with substantially worse diaphragmatic function postoperatively than are lower abdominal operations, and the risk of postoperative pulmonary complications is accordingly higher by a factor of 1.5. [18]
All these changes are favorable for producing postoperative pulmonary complications. These changes are mainly due to altered pattern of ventilation in postoperative period.

Intergroup statistical analysis showed that male patients are more severely affected than female patients. Various reasons that can be put forward for this difference are
1)Type of breathing [10] , Normally during quiet respiration males show abdomino-thoracic type of breathing, while females have thoraco-abdominal type of breathing. Thus abdominal component is predominant in males and this abdominal component is mainly affected during laparotomy.

As the students progress through the school grades the amount of homework and backpack loads of school age children increases. As a result the students carry all their materials in book bags. This has lead to physical complaints in the form of muscle soreness (67.1%), back pain (50.8%), numbness (24.5%) and shoulder pain (14.7%). The most commonly reported medical problem is plexus or peripheral nerve injury. Physical examination can often reveal weakness, numbness and possible muscle atrophy. 3 The Backpack loading produce changes in standing posture when compared with unloaded standing posture which has been related to spinal Althoughpain.4itis

our children to do well in school.7 To initiate an educational program regarding school backpack safety in our area, it is essential to know the ‘weight’ of backpack students are currently carrying. This information could be incorporated into school curriculum or distributed as a handout for children to take home to their parents. Many researches have been done on amount of load carried by student and their effect on shoulder and neck alignment is between 10% and 17% of students’ body weight.1
The previous study done by Chansirinukor et al1 showed that carrying a load of less than 15% of body weight should be recommended, but none of study has shown the particular amount of backpack weight, from where the change in craniohorizontal and carniovertebral angle starts which leads to change in cervical and shoulder posture.
The Backpack is one of several forms of manual load carriage that provides versality and is often used by hikers, backpackers, and soldiers as well as school student. The Backpack is an appropriate way to load the spine closely and symmetrically, whilst maintaining the stability. However, musculoskeletal problems associated with backpack use have become an increasing concern with school children.1
Evaluation of Standardized Backpack weight and its Effect on Shoulder & Neck Posture
Furjuouh el al5 reported that backpack carried by majority of school students, in the sample are no longer heavier than 10% of body weight which is associated with complaints of pain in back, shoulder, neck or other areas of body. Pascoe et al6 reported that mean weight of school bags was 17% of students mean body weight.

Chansirinukor et al6 suggested that a backpack load of 15% body weight is too heavy for adolescents to maintain a prolonged standing posture.
The Backpack is one of several forms of manual load carriage that provides versality and is often used by hikers, backpackers, and soldiers as well as school student. Students have emerged as another population of backpackers who carry their school supplies in book bags which are backpacks. As the students progress through the school grades the amount of homework and backpack loads of school age children increases. We all want our children to do well in school.16 To initiate an educational program regarding school backpack safety in our area, it is essential to know the 'weight' of backpack students are currently carrying.
A total of 10 school boys aged between 13 and 17 years old recruited as subjects. They were recruited from the G.N.D public school, Dehradun. This study was conducted at gymnasium of Dolphin Institute, Dehradun.

There might be reason that different position adopted for measurement might have contributed to contrasting outcome. So further studies using a 3dimensional approach is required to identify the relationship between body landmark and their correct placement for sagittal shoulder posture.
Girls students were not included in the study, because of exposure. As the spine is maturing, there may be gender based difference which can affect the results of the study.

There is lot of controversy about the accurate anatomical landmarks of this angle according to different authors. Based on Rainey and Twomey’s study (1994)1,12, a more rounded shoulder is represented by a smaller sagittal shoulder angle; provided the position
According to National Back Pain Association (1997) and Voll & Klimt11 (1997) who recommended that school children should carry no more than 10% of their body weight, supporting this study. But change in anterior head alignment in present study starts at 13% of body weight which is against the study done by Voll and Klimt.For
For all three angles i.e craniohorizantal angle, carniovertebral angle and anterior head alignment, the change starts at 9%,11% and 13% respectively, which is less than 15% of body weight. According to Chansirinukor et al (2001), who recommended that 15% of body weight represent an overload to this age of young children support the present study.

Previous studies suggest that postural response in high school students are sensitive to load carriage equivalent to 15% of body weight. The amount of weight that does not change the student’s head and neck posture, that can be recommended lies between 9-10% of body weight. So, up to 10% of body weight, there is safeguard limit for adolescents.

Background: Osteoarthritis is a chronic, localized joint disease affecting approximately one-third of adults, with the disease prevalence increasing with advancing age. OA affects many joints including the large, weight bearing joints of the hips and knees and also the spine, hands, feet and shoulders. The knee is the most common weight bearing joint affected by OA, with the disease predominantly affecting the medial compartment of the tibio-femoral joint. Patients with knee OA frequently report symptoms of knee pain and stiffness as well as difficulty with activities of daily living such as walking, stairclimbing and house keeping.
ABSTRACT
Nishant H Nar Consultant Physiotherapist Wockhardt Hospital, Rajkot
The term arthritis literally means inflammation of a joint, but is generally used to describe any condition in which there is damage to the cartilage. The cartilage coats the joint surfaces to absorb stress, and allow smooth joint movement. The proportion of cartilage damage and synovial inflammation (the lining and fluid in the joint capsule) varies with the type and stage of arthritis. Usually the early pain is due to inflammation. Later in the disease, pain is from the irritation of the worn joint structures and inability of the joint to move properly.Osteoarthritis
(OA) is a chronic, localized joint disease affecting approximately one-third of adults, with
Results: The results were analyzed by Wilcoxon Signed Rank Test. Group A showed significant improvement in pain (T=120, p<0.05) and physical function (T=120, p<0.05). In Group B, results showed significant improvement in pain (T=91, p<0.05) and physical function (T=120, p<0.05).

the disease prevalence increasing with advancing age[1]. Concomitant with this high prevalence is a large economic cost, with direct and indirect costs estimated to be $23.9 billion in Australia in 2007[2]. Indeed, given the changing demographics of the adult population[3], expectations are for the prevalence of disease and its burden on the health care system to increase in coming decades[4]Theknee is the most common weight bearing joint affected by OA, with the disease predominantly affecting the medial compartment of the tibio-femoral joint [5,6] . Patients with knee OA frequently report symptoms of knee pain and stiffness as well as difficulty with activities of daily living such as walking, stairclimbing and house-keeping[7].
There are several reasons for the development of OA including age, being overweight, heredity factors, and joint damage from a previous injury or during early development of a joint. Increased loading across the joint has been implicated in the progression of knee OA severity [11] . In knee OA, the medial tibiofemoral compartment is the most common site of disease. The susceptibility of the medial compartment to OA development may relate to greater load distribution (i.e., 60–80%) to the medial than the lateral compartment, even in healthy knees, during gait. Excessive medial compartment loading is widely believed to contribute to medial OA progression. Because direct measurement of knee load is invasive, external knee adduction moment during gait, a correlate of medial load, has been used in knee OA studies[12]. The role of gait analysis in the quantification of dynamic joint load has received much attention in the literature in light of the difficulty in performing in vivo measurement of joint loading during movement[13, 14, 15]. From the research, the external knee adduction moment, an indirect measure of load in the medial compartment of the tibio-femoral joint[16], has emerged as an important and widely accepted biomechanical marker of knee load.
An Experimental study was conducted to study the effects of hip abductor muscle strengthening exercises in patients with osteoarthritic knee joints.
1)To determine the effectiveness of hip abductor muscle strengthening in people with medial compartment knee osteoarthritis.
To date, most knee OA research examining treatment for knee OA has focused on surgical or pharmacological strategies. Although effective, these types of interventions have many potential side effects and are expensive[8]. Thus, recent knee OA clinical guidelines reinforce the importance of non-pharmacological strategies in the management of the condition [9,10] . However, there is an absence of high quality evidence to support the use of such therapies[9].
Study Setting
Study Duration
The sample size of 30 (thirty) patients was divided in to two groups.
2)To compare the effectiveness of hip abductor muscle strengthening and conventional treatment with conventional treatment in people with medial compartment knee osteoarthritis.
STUDY DESIGN AND MATERIALS
Cross-sectional studies demonstrate that patients with knee OA have a higher peak knee adduction moment during walking when compared to healthy agematched controls[17, 18]. It is also likely that the higher prevalence of medial compared with lateral tibiofemoral joint OA is the result of differences in the relative loading within the tibiofemoral joint. The external knee adduction moment determines load distribution across the medial and lateral tibial plateaus[12, 19, 20], with force across the medial compartment almost 2.5 times that of the lateral[16]. It has also been reported that for patients with knee OA, the magnitude of the adduction moment is predictive of clinical outcomes such as severity of knee pain and radiographic disease[21, 22].
as well as more specific programs involving strengthening of particular muscle groups and/or flexibility exercises.

INTRODUCTION
Result: Results show that Scapular Stabilization Exercises showed a significant improvement Shoulder Pain and Disability Index (SPADI sub scores and total scores), when compared to Taping in individuals with Subacromial Impingement Syndrome.
Background & purpose: Shoulder disorders are among the most common of all peripheral joint complaints1,2, with Subacromial Impingement Syndrome considered to be one of the most common forms of shoulder pathology3, accounting for 44% to 60% of all complaints of shoulder pain during arm elevation or overhead activities4. Researches for Subacromial Impingement Syndrome due to Scapular Dyskinesis show that scapular stabilization exercises provide good results39. On the other hand one of the study shows that effect of changing posture by taping will reduce the symptoms of Subacromial Impingement Syndrome41. So the study is to compare the effectiveness of Scapular Stabilization Exercises and Taping in improving shoulder pain & disability index in patients with Subacromial Impingement Syndrome due to Scapular Dyskinesis.

Primary shoulder impingement occurs when the rotator cuff tendons, long head of the biceps tendon, glenohumeral joint capsule, and/or subacromial bursa become impinged between the humeral head and anterior acromion8. Secondary shoulder impingement is defined as a relative decrease in the subacromial space due to glenohumeral joint instability or abnormal scapulothoracic kinematics8
Scapular Dyskinesis is the alteration in the normal static or dynamic position or motion of the scapula during coupled scapula-humeral movements. Other names given to this catch-all phrase include: “Floating Scapula” and “Lateral Scapular Slide”10.

The scapular muscles facilitate upper extremity movement via the scapular motions of protraction, retraction, upward (lateral) rotation, and downward (medial) rotation. The main muscles providing scapular stabilization are the rhomboids, trapezius, and serratus anterior17. Researches for Subacromial Impingement Syndrome due to Scapular Dyskinesis show that scapular stabilization exercises provide good results39. One of the study shows that effect of changing posture by taping will reduce the symptoms of Subacromial Impingement Syndrome12. Taping is particularly useful in addressing movement faults at the scapula-thoracic, gleno-humeral and acromio-clavicular joints 13. The basic rationale for taping is to provide protection and support for a joint while permitting optimal functional movement. It is assumed that external support increases joint stability by reinforcing the ligaments and restricting motions14.

3.Shoulder Pain And Disability Index. Assessment of Pain and Disability Evaluation.
Pain and disability is evaluated by using SPADI. It consists of 2 self report sub scales of pain and disability. The items of both scales are VAS (Visual Analogue Scale) and the 5 items pain subscales asks people about their pain during ADLs (Activities of Daily Livings) and each item is anchored by the descriptions “no pain” (left anchor) and “ worst pain imaginable” (right anchor). The 8 disability items ask people about their difficulty in performing ADL. Higher scores on the sub scale indicate greater pain and greater disability. To obtain the total score of SPADI both the pain and disability subscales are averaged.
For Lower Trapezius
From anterior aspect of upper trapezius just above the clavicle over the muscle belly to approximately the level of rib seven in a vertical line. Once partially attached, a firm downward pull is applied and the tail of the tape attached.

Subacromial impingement syndrome is caused by narrowing of the subacromial space with secondary impingement of the bursal surface of the rotator cuff on the undersurface of the acromion16. Some evidence exists that, Scapular dysfunction is associated with Shoulder
A potential mechanism by which proprioceptive shoulder taping may be effective is via augmented cutaneous input. Tape is applied in such a way that there is little or no tension while the body part is held or moved in the desired position or plane. It will therefore develop more tension when movement occurs outside of these parameters. This tension will be sensed consciously thus giving a stimulus to the patient to correct the movement pattern. Over time and with enough repetition and feedback, these patterns can become learned components of the motor engrams for given movements. It also causes increase in length and decrease in tension thereby producing greater force development in the inner range through optimised actinmyosin overlap during the cross-bridge cycle13. One of the study demonstrated that taping was effective in decreasing Upper Trapezius and increasing Lower Trapezius activity in individuals with shoulder impingement during overhead reaching tasks, thus improving scapular dyskinesis15.

Therapeutic exercises have previously been determined to have long-term benefits for patients with shoulder impingement syndrome8. The therapeutic exercise stretches the anterior and posterior shoulder girdle, relaxes the muscle, helps in motor learning to normalize dysfunctional patterns of motion, and strengthening the rotator cuff and scapular muscles, which leads to improvements in pain, levels of disability and functional loss, strength, shoulder range of motion, pain with subacromial compression4.

Chronic obstructive pulmonary disease (COPD) is currently the fourth leading cause of death worldwide. The male to female ratio varied from 1.32:1 to 2.6:1 with median ratio of 1.6:11
Chronic obstructive pulmonary disease (COPD) refers to a group of disorders characterized by chronic airflow obstruction/limitation. It includes two distinct patho-physiological processes—chronic bronchitis and emphysema1, 2, 3, 4. It is associated with an abnormal inflammatory response of the lungs to noxious particles or gases, especially tobacco smoke and air pollutionboth indoor and outdoor.
The disadvantages of bio mechanical alterations of hyperinflation are compounded by the increased demand for ventilation in COPD. More work is required of a less effective system. The energy cost of ventilation,

Method: Patients were selected from the respiratory OPD at a tertiary care centre using convenience sampling technique. The patients were recruited after signing the ethics approved consent forms. Outcome measures: chest expansion, peak expiratory flow rate and respiratory rate were assessed and documented prior to and following the intervention. The subjects were given seven osteopathic manipulative techniques. The entire duration for osteopathic manipulative treatment session was approximately 20 minutes for each subject.
Conclusion: Osteopathic manipulative treatment increases chest expansion at both axillary and xiphisternal level and peak expiratory flow rate and leads to reduction in respiratory rate in patients with COPD.
ABSTRACT
Background: The study was carried out to assess the effects of osteopathic manipulative treatment in patients with chronic obstructive pulmonary disease.
management of COPD includes smoking cessation, pharmacological therapy, long-term oxygen therapy, and pulmonary rehabilitation. COPD have been shown to decrease compliance of the chest wall, force-generating capacity of the diaphragm, residual volume (RV) increases, and forced vital capacity (FVC). Therefore, the therapeutic intervention commonly done for chest wall and related structures are respiratory muscle stretching exercises. They have been reported to improve chest wall mobility, improve vital capacity, and decrease dyspnea6. However, COPD is an important disease whose incidence is rising worldwide and that there is a need to develop new treatments to prevent the progression of the disease7

of osteopathic technique by Laurie Hartman, kneading of paraspinal muscles relax them by reducing fluid congestion and tonic irritability. The underlying mechanism is thought to be due to reflex balancing or from fluid interchange and lymphatic drainage within the tissues12. Luce Helen and Robinson Mark stated that soft tissue kneading decreases muscle spasm, stretches and improves elasticity of soft tissues, improves circulation, improves venous and lymphatic drainage and promotes relaxation13.
Principles and practices of therapeutic massage by Sinha states that kneading produces a local increase in the flow of blood due to pumping action, liberation of H substance and elicitation of axon reflex. This also decreases the stagnation of fluid and oedema as well as improves the nutrition of the area. It stretches the tight fascia and helps in restoration of mobility of skin and subcutaneous fascia. The intermittent pressure may also stimulate tension dependent mechanoreceptor, i.e. Golgi tendon organ, etc. and decreases the excitability of motoneuronal pool in neurologically healthy

The ventilation depends on the rib motion, diaphragm function, muscles of respiration and mechanical properties of the airways10 In COPD there is hyperinflation of lungs and therefore chest wall is fixed in inspiration (barrel shaped chest) 11 This results in shortening of soft tissue of upper chest. COPD patients generally have a kyphotic posture with rounded shoulders (pectoral tightness) and elevated shoulder girdle (trapezius tightness) to effectively use accessory muscle of respiration. When the muscles are in a shortened position, the fascia overlying the muscle also gets shortened. Due to the barrel shaped chest, the ribs are horizontally oriented. This further reduces the

The results of the present study indicate that there is statistically significant increase in chest expansion at axillary and xiphisternal level. Also an increase is seen in peak expiratory flow rate and decrease in respiratory rate after osteopathic manipulative treatment, thereby supporting the experimental hypothesis.

The reduction in RR could be attributed to normalization of sympathetic tone through Chapman’s reflexes. The increase in chest expansion probably suggests that the patients tidal breathing has increased and therefore reflected as reduced RR.

Conclusion: Osteopathic manipulative treatment increases chest expansion at both axillary and xiphisternal level in patients with COPD. There is increase in peak expiratory flow rate following osteopathic manipulative treatment in patients with COPD. Osteopathic manipulative treatment leads to reduction in respiratory rate in patients with COPD.
In COPD there is increase in sympathetic nervous system activity leads to release of catecholamines into the blood stream and there is narrowing of airways which leads to reduction in peak expiratory flow rate.7 Paraspinal muscle kneading and rib raising probably stimulate Chapman’s reflexes. Suboccipital decompression probably improves parasympathetic function by releasesing restricted tissues around vagus nerves. 13, 16 This may lead to normalization of sympathetic tone and which in turn may increase PEFR and reduce RR.
and Kuchera have this to say regarding lymphatic drainage and the lungs.
Myofascial release techniques such as diaphragm release and thoracic inlet release also contributes to increase in chest expansion and improves motion of diaphragm. It releases connective tissue tension within structures of thorax. It helps in removing restriction to lymphatic flow. It releases tissue restriction, improves lymphatic drainage and improves mechanics of respiration.11,According14to
Effective lymphatic drainage of the lungs is normally achieved by contraction of the diaphragm and thoracic cage movement during respiration. However, in patients with COPD, both of these mechanisms may be compromised, leading to impaired lymphatic drainage. There are several OMT techniques which address the problem of lymphatics such as rib raising, diaphragm release, and lymphatic pumps18.

traction technique, a Myofascial release technique, also helps in increasing chest expansion by lengthening the tight structures12.The combination of traction and respiratory motion releases the upper anterior thoracic muscle tension15.
The American Academy of Osteopathy states that the rib raising technique improves movement of ribs and thoracic cage by mechanical stimulation of sympathetic chain ganglia and related structures. This results in improved sympathetic tone in lung. This is supported by the study done by Aaron T. Henderson which shows that sympathetic nervous system activity may decrease immediately after rib raising17.

Back ground: Adhesive capsulitis, most commonly referred to as frozen shoulder (FS), is an idiopathic disease with 2 principal characteristics: pain and contracture, affecting the external rotation most. In contrast to traditional mobilization technique andrea et al found posterior glide more effective in improving external rotation ROM and pain.
Objective: To find out the effective stretch glide for external rotation ROM and pain in patients with primary adhesive capsulitis.
Traditionally anterior glide of GH joint is used to improve External Rotation ROM based on convex concave concept.10 Where as Roubal11 and Andrea J12 et al have found posterior glide more effective based on capsular constrain mechanism.13

ABSTRACT
Keywords: Primary Adhesive Capsulitis, Stretch Glides, External Rotation
Frozen shoulder, or idiopathic adhesive capsulitis is a condition of uncertain etiology characterized by substantial restriction of both active and passive shoulder motion that occurs in the absence of a known intrinsic shoulder disorder1
The types of treatment have included benign neglect, chiropractic manipulation, oral corticosteroids, injection of corticosteroids, physical therapy exercises and modalities, manipulation under anesthesia, mobilization and arthroscopic and open releases of the contracture2-6Adhesive
Methods: 30 subjects were divided into two groups called Anterior stretch glide (ASG) and Posterior stretch glide (PSG). Each group received ultrasound, same exercise protocol along with their designated glides for 2 weeks. Outcome measures were External Rotation ROM and VAS. Data was analyzed by using the SPSS software. Wilcoxon signed rank and rank sum tests were used to measure the differences in VAS and Paired and unpaired t tests were used for ROM evaluation.
Comparison of Stretch Glides on External Rotation Range of Motion in patients with Primary Adhesive Capsulitis
INTRODUCTION
Findings: There was a significant difference in External Rotation ROM and VAS in both the groups after the intervention, even there is a significant difference between the groups.

Conclusion: anterior stretch glide is very effective in reducing pain or unpleasantness intensity and increasing external rotation range of motion at shoulder in patients with primary adhesive capsulitis.
does not become adhered to the humerus, as the term adhesive implied, but the contracted capsule holds the humeral head tightly against the glenoid fossa. Clinically, there is global loss of both passive and active ROM of the glenohumeral joint, with external rotation usually being the most restricted physiologic movement.2,7,8Inphysiotherapy
exercises, massage and modalities have been shown effective to improve ROM at shoulder joint, except rotational components. 9
Purpose of this study was to find out the direction of movement for GH joint glide that would result in significant improvement in shoulder External rotation ROM in individual with primary adhesive capsulitis.

For each subject, the number corresponding to the subject’s mark on the visual analogue scale was recorded. Raw score means and standard deviations of the visual analogue scale score and external rotation range of motion were calculated. In order to determine whether there was a significant difference within the two groups between the pre-treatment visual analogue scale scores and the post treatment visual analogue scale scores, Wilcoxon Signed Rank Test was performed. The difference between pretreatment visual analogue scale scores and post treatment visual analogue scale scores in ASG group was compared with that of PSG group using Wilcoxon Rank Sum Test. This analysis was done to determine whether the difference in the scores between the two groups is significant or not. The pretreatment external rotation range of motion was compared with the post treatment external rotation range of motion within two groups using two tailed Student’s paired t-test. Between groups comparison of difference in external rotation range of motion was done by performing two tailed student’s unpaired t-test. The paired and unpaired t-tests were performed using spss statistics 14.0.
Targeted capsule (anterior or posterior) was preheated before glide by 1 MHz 19Ultrasound, in order get the maximum effect of stretch glide.17 Ultrasound were applied at 1.5 w/cm2 in continuous mode for 10 minutes (Electroson 608, 35mm diameter of head, 12 acoustic watts max). Capsule region was effectively covered and subjects were asked to report discomfort if any. However no such reports were found during the study.Inthis
Subjects were positioned in supine; with maintained lateral humeral distraction (mid range position), while posterior stretch glide was performed to end range, at the end range of abduction and external rotation.
Followed by the stretch glides subjects were participated in traditional ROM exercises which include rope and pulley, finger ladder, wand exercises, pendular exercises 20 repetitions for each exercise.

RESULTS
et al7 studied the gleno-humeral joint in vitro using techniques in which only the capsule and articular surface contact controlled the motion of the humerus. They found that at low mo-ments the humeral head initially trans-lates across the glenoid surface in the direction opposite to the motion, due to the joint surface geometry, as consistent with the concave-convex rule. Then, with increasing moment and angle of rota-tion, the humeral head changes direc-tion as the capsule tightens, “pushing the humeral head back along the glenoid surface.” Thus, it is thought that the tension in the capsular tissues rather than joint surface geometry controls the translatory movements of the humeral head. Asymmetrical capsular tight-ness has the potential to impact humeral head motion, especially
There was no significant age difference seen across two groups.

Wilcoxon Rank Sum Test (Mann Whitney ‘U’ Test) was applied for comparison between ASG and PSG for post treatment visual analogue scale scores. The result reflects significant difference in the improvement between ASG and PSG Groups
DISCUSSION
Study was done to investigate the effectiveness of anterior versus posterior stretch glide on External Rotation ROM and pain or unpleasantness in patients with adhesive capsulitis. We found that anterior stretch glide combined with ultrasound and exercises were superior in treating External Rotation ROM deficits commonly found in patients with adhesive capsulitis.
The two tailed paired t-test has showed significant difference between pre and post-treatment external rotation range of motion in ASG and PSG group at 5% significant limit. Comparison showed significant difference between these groups. Calculated t values for the difference of External rotation ROM within ASG & PSG groups at 5% significance limit and t values for comparison of difference between two groups and value of probability of occurance by chance.

We have excluded the patients who have muscular tightness affecting the study. i.e. subscapularis. Glenohumeral external rotation ROM deficit was attributed to muscle flexibil-ity deficit (eg, subscapularis flexibility deficits) if the glenohumeral external rotation ROM deficit became less as the shoulder was abducted.12Thesefindings
are against of Roubal11 et al and Andrea12 et al, who found marked increase in External Rotation ROM with posterior glide. Our findings support the traditional convex concave rule.13, 18
Andrea et al have chosen flexion as additional component to increase effectiveness for mobilization using posterior stretch glide which could have affected their outcome; where as we have not added the flexion in posterior glide no matter whatever the progression is. Present study includes only those patients who have finished the protocol despite having vigorous stretch protocol for 1 min at least without compromising the intensity of stretching; where as Andrea et al have used the vigorous protocol in a minimal number of patients only.Novotny
Above results suggests that anterior stretch glide is more effective in improving shoulder external rotation and pain or unpleasantness as compared to posterior stretch glide.
Table 1 shows the gender distributions and mean age with standard deviations respectively. ASG group contained 6 (40%) male and 9 (60%) female with mean age of 43.095±11.38 years, where as PSG group contained 5 (33%) male and 10 (67%) female with mean age of 44.295±10.6 years.
Wilcoxon signed rank test was applied in ASG and PSG group for within group comparison of visual analogue scale score and the result showed significant improvement in visual analogue scale scores in ASG (T=110>105, P<0.01) and PSG (T=60, P<0.05)
Hence, the null hypothesis of no difference within and between groups is rejected and alternative hypothesis is accepted.

Joint mobilization techniques are assumed to induce various beneficial effects. The neurophysiologic effect is based on the stimulation of peripheral mechanoreceptors and the inhibition of nociceptors. In addition obermann et al found high grade traditional mobilization found effective to treat the patients with primary adhesive capsulitis.20 Our results supports it in terms of pain and ROM.

We found anterior stretch glide more effective based on traditional covex concave rule and naturally elongated anterior capsule provide more space for head of humerus when subject actively externally rotate the arm in contrast to capsular constrain mechanism.13 Moreover in adhesive capsulitis fibrous adhesion takes place surrounding the joint capsule, we believe that anterior stretch glide may be more effective in breaking those adhesion and allow normal kinetics when patient attempts active external rotation.7
LIMITATIONS
Dominance of hand is of much importance in adhesive capsulitis, we have not considered it in our study.Abduction and Internal Rotation could have included in this study as outcome measures.
Functional outcome measure was not included in this study.

A Study of Electromyographic Activity of Masseter Muscle After Gum Chewing in Young Adults
ABSTRACT
Results: The independent t-test indicates a significant increase in the motor activity of the masseter muscle in females than in males as t-test reveal statistically reliable difference between the mean number of POST TEST - A has (M = 2.171, s = 101.76) and that the POST TEST - B has (M = 1.62, s = 75.57), t(58) = 2.367, P = .05.
The Masseter muscle is an integral part of the oral facial complex and one of the major muscles of mastication. It functions with other masticatory muscles
Subjects: 60 young adults (30 females and 30 males) who do gum chewing took part in this study which was allotted to two groups: Group A- Females and Group B- Males.
Aims and Objective: To compare the effect of gum chewing on masseter muscle in females with males by analyzing its electromyographic behaviour.
INTRODUCTION
208 Indian Journal of Physiotherapy & Occupational Therapy. January-March 2013, Vol. 7, No. 1
Chewing is an oral function that is of vital importance for the biological and social life of human beings. As a pre-requisite for this function, a healthy masticatory system characterized by the absence of pain at rest and during functional movements of the mandible is required.1, 2
in moving and posturing the mandible. When a patient has temporomandibular dysfunction (TMD) or a myogenic disorder, the integrity of the masseter muscle can be compromised resulting in pain, malfunction, inflammation and swelling. TMJ syndrome occurs in younger patients mostly women, typically between the ages of 20 and 40. A careful evaluation of the masseter muscle is necessary in facial pain patients since the pain can originate from a distant site and be referred to this area.3, 4, 5, 6
Background: Habitual gum chewing is considered as one of the causes which can lead to the development of Temporomandibular disorder (TMD). Previous studies have compared the effect of chewing induced masticatory muscle pain in females and males using different methods but this study compares the electromyographic behaviour of masseter muscle in females with males who do gum chewing.
Research Design: Comparative study
Methodology: The device used in this study is a single channel EMG. The subjects were given chewing gum and asked to chew gum at least one hour before coming for the study. All monitoring was performed with the patients in a sitting position. Two self-adhesive surface electrodes were utilized and placed on the midsubstance of muscle belly of right masseter muscle in line with muscle fibers. The EMG recording of masseter muscle was done at most comfortable position of jaw i.e., at rest position and the EMG activity was recorded after 30 seconds.
Conclusion: Electromyographic behaviour of the masseter muscle in individuals who do gum chewing is found to be significantly increased in females than in males. This can result in the development of the signs and symptoms of the temporomandibular disorders. Therefore, it can be concluded from the present study that one should avoid gum chewing especially females on the regular basis so as to prevent their jaw from the risk of developing TMD at an early age.
Data Analysis: Data are expressed as mean, standard deviation and 95% confidence interval. The independent t- test or Levene's test for equality of variances was used to determine the normal distribution of the variance (P < 0.05).

further research must be done on these possible negative side effects of constant gum chewing. But for now, the idea of research is to study the longterm effects of gum chewing on motor activity of the masseter muscle by comparing its electromyographic behaviour in females with males who do gum chewing.
•History of orthognatic surgery.
Gum Chewing like any product has positive and negative effects. Surprisingly, the positive effects of gum chewing are many; however excessive use can present problems. The type and duration of chewing are what determine how healthy or unhealthy gum chewing will be for an Womenindividual.6aremorelikely to experience disability due to TMDs, and they represent over 80% of the patients who receive treatment of TMDs.9, 10 In 2003; H. Karibel, G. Goddard and R. W. Gear11 studied the sex differences in masticatory muscle pain after chewing. They tested the hypothesis that physiologically relevant exercise (i.e., chewing bubble gum for 6 min) increases masticatory muscle pain in patients, but not in asymptomatic control subjects, and that female patient’s experience a significantly greater increase than males. These results suggested greater susceptibility in women.Obviously,

PROCEDURE
The subjects for the present study were selected from various colleges of Delhi. 60 young adults (Group A30 females and Group B- 30 males) took part in this study on the basis of following criteria:
•Free of dental pathologies.
•Age group of 20 to 25 years.
•Medical systemic problems that could affect muscular function such as myalgia, myositis and fibromyalgia of masseter muscle.

CONCLUSION
Electromyographic behaviour of the masseter muscle in individuals who do gum chewing is found to be significantly increased in females than in males. The independent t-test indicates that females show higher electromyographic activity of masseter muscle than males which means masseter muscle functions at a higher pace in females who chew gum continuously which may lead to the wear and tear of the temporomandibular joint. This can result in the development of the signs and symptoms of the temporomandibular disorders.1 Therefore, it can be concluded from the present study that one should avoid gum chewing especially females on the regular basis so as to prevent their jaw from the risk of developing TMD at an early

effect of gum chewing on motor activity of the masseter muscle which is considered as the primary chewing muscle was compared in females with males who do gum chewing using EMG since it is well known that the amplitude of EMG is related to certain extent to the force a muscle may generate.15, 24 The temporomandibular joint is used throughout the day to move the jaw, especially in biting, chewing, talking and yawning. Slow and painful failure of jaw joint function is termed as temporomandibular syndrome/disorder. Habitual gum chewing is considered as one of the causes which can lead to the development of TMJ disorders.25 In this study we found
The device used in this study is a single channel EMG. The subjects of both the groups were given chewing gum and asked to chew gum at least one hour before coming for the study. All monitoring was performed with the patients in a sitting position. The subjects were seated comfortably upright in a chair of adjustable height at a desk of 30-inch height on which the EMG attached to an desktop display is placed.17 Back of their heads were supported and their feet was insulated from the floor.18 The subjects were asked to make no head or body movements during the recordings.19 Position of the head was kept vertical and no movement was allowed as jaw muscles respond to change in head position 20, 21 and facial muscles should be relaxed, keeping lips closed. Questions were answered after the instructions were given to be certain that the instructions were understood. Two selfadhesive surface electrodes were utilized and placed on the midsubstance of muscle belly of right masseter muscle in line with muscle fibers. 22, 23 One electrode was at the level of the lower border of the mandible, and the other 25 mm above this, close to the motor point. Preliminary experiments showed that with this placement, the waveform obtained by triggering an average of the surface EMG on the spikes of a single masseter motor unit was biphasic and approximately symmetrical. 23 The EMG recording of masseter muscle was done at most comfortable position of jaw (i.e., at rest position which is the habitual postural position of the mandible when at rest is in the upright position and the condyles are in a neutral unstrained position in the mandibular fossae). It was made sure that proper electrode placement is done and then EMG activity was recorded. The recording time for each analysis was 30 seconds.

DATA ANALYSIS
For most people, pain in the area of the jaw joint or muscles does not signal a serious problem. Generally, discomfort from these conditions is occasional and temporary, often occurring in cycles. The pain eventually goes away with little or no treatment. Some people, however, develop significant, long-term symptoms.4,9 Many studies have also shown that women show a tendency to report significantly elevated levels of muscle pain after a heavy chewing exercise, while men do not.11 But, still neither the etiology of muscle related temporomandibular disorders nor the reason for the disproportionate number of women suffering from these disorders is well established.

significant increase in the activity of masseter muscle in females who do gum chewing for prolonged time.
Many other conditions can cause similar symptoms to TMD – including a toothache, sinus problems, arthritis, or gum disease. Therefore, health professional needs to conduct a careful patient history and clinical examination to determine the cause of the symptoms.9 Researchers throughout the health sciences are working together not only to gain a better understanding of the temporomandibular joint and muscle disease process, but also to improve the quality of life for people affected by these disorders. Simple self-care activities are often effective in maintaining oral health and also preventing jaw from the risk of developing TMDs. Nowadays, gum chewing is considered as the major culprit as it leads to the over usage of the jaw therefore it should be avoided.

Further research is of course required but the present study suggests that one should avoid gum chewing on the regular basis especially females as continuous chewing has a harmful effect on the masseter muscle activity. In individuals who do continuous chewing, masseter muscle continues to function at a higher pace getting no time to recover between the meals. Thus, gradually it can lead to the development of signs and symptoms of temporomandibular disorders.

Aims & Objectives: A study to investigate the effect of fatigue on knee joint proprioception and balance in healthy individuals.
Materials & Methods: An observational study was conducted on 30 healthy subjects ( age 18-30 years) from Srinivas college of physiotherapy, Mangalore. Subjects was selected by simple random sampling techniques. Fatigue was induced in the subjects by cycling upto level of exceeding 60% of predicted HRmax (14-17 PRE). Subjects were tested to estimate reproduction error by using weight bearing joint position sense test at 30 0 of knee flexion , by goniometric evaluation accompanied by photographic method and the balance assessment was done on force platform with the measurement of anteroposterior, lateral CoP excursion and stability score in single limb stance, before and after fatigue protocol.
Results: After inducing fatigue,significant reproduction error was found for perception of joint position sense (t=-4.103) with significant changes were found in AP (t=3.997), lat CoP excursion (t=10.949) and stability score (t=11.785) at p>0.05.
altered ability to dynamically stabilize the knee joint but exactly how this impairment comes about is less clear. 6 It is possible that one factor is reduced proprioceptive acuity.7
Muscular fatigue is most often defined as an exercise induced reduction in the ability of a muscle to generate force. 1 It is caused by a combination of different physiological mechanisms occurring at both the central through the impairment of central drive and peripheral level through the impairment of muscle function.2 The high incidence of injuries occur during later session of sports suggest that fatigue may predispose a joint to injury and decrease the athletic performance.3 The study of fatigue relative to performance of different skills in the sports has long been a subject of practical interest.4
In 1906, Sherrington defined “Proprioception” as the perception of positions and movements of the body segments in relation to each other, without the aid of vision, touch or the organs of equilibrium. 7 The importance of the proprioception in knee function, stability, injury prevention has been studied extensively in literatures. The current consensus is that the sense of proprioception originates in the simultaneous activity of a range of different types of receptors located in muscles, joints, and skin.8 Some of these receptors have been shown in animal studies to be affected by muscle fatigue 9 and/or by increased intramuscular concentrations of substances (Arachnoid acid, KCL, 5HT, Bradykinin) released during muscle contractions10 which have a direct impact on the discharge pattern of muscle spindles that represent the peripheral
ABSTRACT

Introduction: Balance and proprioceptive testing is more commonly used in clinical settings to evaluate injured athletes to return to activity. Muscle fatigue produces neuromuscular deficiency within the muscle , thus predispose a joint to injury and decrease the athletic performance. A finding of previous studies shows contradictory findings of effect of muscle fatigue on proprioception and balance.
Conclusion: A study revealed that moderate exercises can reduce proprioception which affects the neuromuscular control of joint making individual more suspectible to injury.
INTRODUCTION
Keywords: Fatigue, Proprioception, Balance, Dynamic Stability.
Since sports activities are strongly promoted, the risk of sport injuries is likely to increase. It is reported that knee joint injuries are the common injuries among all sports injury, 39.8% of all sports injuries involve the knee.5 It has been suggested that a higher incidence of injuries at the last third of match could be related to alteration of the lower limb neuromuscular control and
component of fatigue and efferent as well as afferent neuromuscular pathways are modulated with excessive fatigue via reflexes originating from smalldiameter muscle afferents (group III and IV afferents) could modify the central processing of proprioception.11 Although it is reasonable to assume that these receptors are affected in a similar way in humans, comparably little is known about the fatigue effects on human proprioception.12Theperception of movement or joint position in clinical measurements reflects the status of the whole system, or that measured proprioceptive defects are connected to functional disability.13 It is believed that the Central Nervous System (CNS) links together afferent proprioceptive feedback from multiple joints of a limb segment and redundancy of the afferent information can be used as an “error check” to improve proprioceptive feedback in order to maintain function.8 Reproduction ability is decreased; possibly due to increased sensitivity of capsular receptors from muscle fatigue-induced laxity.3 The assessment of potential injury risk before sports participation followed by intervention may decrease the relative injury incidence in athletes.14Theintegrity

and control of the proprioceptive acuity is essential for the maintenance of balance.15 Balance is defined as person’s ability to maintain an appropriate relationship between the body segments and between the body and the environment and to keep the body’s center of mass over the base of support when performing a task.16 It is assumed that some form of muscle spindle desensitization or perhaps ligament relaxation and Golgi tendon desensitization occurs with excessive fatigue which leads to decreased efferent muscle response and poorer ability to maintain balance. 17 Balance testing is more commonly used in the clinical setting to establish gains in the proprioceptive capacity of injured limbs and helps to evaluate injured athlete to return to activity.15 Measures of postural control such as center of pressure (CoP) excursion which may be a more sensitive measure of postural control that incorporates proprioception have been used clinicaly.18

In humans, the effect of fatigue on proprioception has been investigated at various joints. Findings of disturbed proprioception and balance are frequent in the literatures, but together they are not conclusive. So the purpose of this study is to investigate the effect of muscular fatigue on proprioception and balance in healthy individuals.

We found that a short period of moderate exercise can reduce proprioception, which may affect the neuromuscular control of the knee joint and significantly affects the ability of an individual to maintain balance on force platform device, thus, may make it more susceptible to injury.

position sense (t = -4.103, p < 0.05) thereby supporting the experimental hypothesis.
The results of the present study also indicated that fatigue reduces balance performance (t= 11.785; p < 0.05). There are several possible reasons why muscular fatigue affects balance performance. It seems plausible that some form of muscle spindle desensitization or perhaps ligament relaxation and Golgi tendon desensitization occurs with excessive fatigue. The increased AP and Lat CoP excursion observed after cycling in the present study may be explained by a
Different methods have been used to assess proprioceptive acuity in various studies. Amongst them, Goniometric evaluation for measuring the angle accompanied by video films is an adequately accurate method of measuring the joint angle. Berry C. Stillman et al. (2001) explained that WB assessments of proprioception which is more functional might have greatest relevance in the area of sports medicine . Theoretically, fatigue may increase the time of reaction, which, in the present study, would be seen as higher reproduction error scores. 20

decrease in muscle response and a delay in muscle reaction and poorer ability to maintain balance.17 Eva Ageberg et al. (2003) found that short-term cycling decrease ability to maintain balance in single limb stance in healthy subjects 30 support the result of present study . 21
The findings of David Roberts et al. (2003) on healthy young persons, to estimate threshold for perception of movement before and after fatigue shows statically significant difference in threshold value, after inducing fatigue which support the results of our study.22 However, Marks and Quinney (1993) provided contradictory findings suggested that muscle fatigue had a negligible effect on knee JPS. However, they induced fatigue by having the subject contract the quadriceps muscle 20 times, which likely was less fatiguing and that mainly affected the anterior structures of the thigh. Therefore, the posterior structures, which are of afferent importance during extension, were probably less affected by fatigue.23
An important issue here in this present study is, whether the effects of fatigue on position sense of knee can be attributed to central fatigue or to muscle fatigue. Central fatigue may have accompanied peripherally elicited effects, but there is a chain of evidence indicating that alterations in the proprioceptive inflow from peripheral muscle receptors have contributed considerably to the central fatigue effects. 10

Conclusion: Our study concluded that there was no statistical significant difference between core stabilization group and balance training group.
Keywords: Core-Stability Training, Balance Training, Neuromuscular Control
Method: subjects were randomly assigned to one of the two groups: Group A-core stabilization group and Group B-Balance training group. Both groups were given exercise program for six days per weeks for two weeks. Pre and post analysis was done by using Star Excursion Balance Test.
Balance is a key component of normal daily activities. In the simplest terms, balance can be defined as “the ability to maintain the body’s centre of gravity within the limits of stability as determined by the base of support”. Balance, or postural control, can be described as either dynamic or static. Static postural control is attempting to maintain a base of support while minimizing movement of body segments and the centre of mass; while dynamic postural control involves the completion of a functional task with purposeful movements without compromising an established base of support.1Tomaintain
Panjabi describes ‘‘clinical instability as the loss of the spine’s ability to maintain its patterns of displacement under physiologic loads so there is no initial or additional neurologic deficit, no major deformity, and no incapacitating pain’’. The spine stability system consists of the following interacting elements Neuromuscular control (neural elements), Passive subsystem (osseous and ligamentous elements) & Active subsystem (muscular elements).3
Result: Paired T-test was used within the group and p value was found to be less than .05 in both the groups and independent sample T-test was used between the groups where p value was found to be more than .05.
The human core is described as the human low backpelvic-hip complex with its governing musculature. The core is important because it is the anatomical location in the body where the centre of gravity is located, thus where movement stems. The core functions to maintain postural alignment and dynamic postural equilibrium during functional activities, which helps to avoid serial distortion patterns. Core stability is the motor control and muscular capacity of the lumbopelvic-hip complex.4

balance, it is necessary to have a functional awareness of the base of support to better accommodate the changing centre of gravity. The goal of balance training is to improve balance through perturbation of the musculoskeletal system that will facilitate neuromuscular capability, readiness, and reaction.2

Introduction: Over the years, injury rehabilitation has changed from strengthening the body using strength training to achieve functional kinetic chain movements using neuromuscular training, which includes balance and proprioception. Neuromuscular control is the motor response to the sensory input of the muscles, whereas balance is a state of bodily equilibrium. The purpose of this study was to find out the effect of core stabilization and balance training on dynamic balance.
INTRODUCTION
Group B received Balance Training exercise of 3 sets for 30 seconds/session once a day 6 days a week for 2 weeks, exercises are Tandem Standing, One Limb Balance, Hip Rise, Knee Band, Standing Kick, Side Kick, Standing On Foam, One Leg Standing On Foam, Back Kick with Band and Side Kick With Band Band.

A useful method of measuring dynamic balance is the Star Excursion Balance Test.1 The test provides a quantifiable way to measure dynamic balance. This single leg standing and contralateral reaching test can be used to determine the dynamic stability of an individual as they perform a functional movement task. SEBT requires a participant to maintain a base of support with one leg while maximally reaching in different directions with the opposite leg without losing balance or significantly altering the base of support in the stance
DATA ANALYSIS AND RESULT
having injury and pathology of Hip, Knee and Ankle, deformities such as Genu valgum & varum etc, Sharp acute pain, recent hematoma of knee, hip & ankle and any acute inflammatory condition, history of LBP with sciatica and subject with neurological impairments were excluded from the study.
Paired T-test was used within the group and p value was found to be less than 0.05 in both the groups. There was significant difference within the groups as seen in Table 1 & Independent2.
Kibler et al, core stability and strength is an important component to maximize efficient balance and athletic function in upper and lower extremity movements. The same authors suggest that the core acts as a base for motion of the distal segments, or “proximal stability for distal mobility.7
Data analysis was done by using SPSS software.
Thus, the aim of this study was to find out the effect of core stability and balance training on dynamic balance.
MATERIALS AND METHOD
All the subjects were explained about the procedure and were made to fill the consent form. Subjects were divided into two groups: Group A (n=15) - Core stabilization group and Group B (n=15) - Balance training group. Pre evaluation was done by using Star Excursion Balance Test.
Logically, strengthening core muscles will improve stability of the lumbar spine. What has been researched in much less detail is the effect core strengthening will have on tasks that encompass whole body movement and dynamic postural control.7
abdominus, internal oblique and quadrates luborum constitute the local stabilizing system. The longissimus thoracis, rectus abdominus and external oblique make up the global system. The local system is responsible for segmental spine stability while the global system is responsible for isometric and isotonic contraction in the spine. Both of these regions play a role not only in daily and athletic movement but also potentially in injury prevention.6
It was an experimental study. Thirty normal healthy subjects of CAEHS, Meerut of both the gender with age 18 to 25 years were included in the study. Subjects
Group A received core stability exercises of 3 sets for 30 seconds/session once a day 6 days a week for 2 weeks. Exercises given to this group were Plank Jao, Side Plank, Bridge, Superman, Sideline Hip Abduction, Oblique Crunch, Straight Leg Rise and Lying Windscreen Wipers Wipers.
After two weeks, both the groups were evaluated again using SEBT.
sample T- test was used between the groups where p value was found to be more than 0.05. There was no statistical significant difference between the groups as seen in table 3.

When the transverse abdominus contracts, the intraabdominal pressure increases and tenses the thoracolumbar fascia. These contractions occur before initiation of limb movement allowing the limbs to have a stable base for motion and muscle activation. The rectus abdominus and oblique abdominals are activated in specific patterns with respect to limb movement that also provide postural support.9

Our study concluded that there was no statistical significant difference between core stabilization and balance training program.
Table 3 Independent T-Test between the Sig.(2-tailed)Groups
This study was an attempt to find out the effect of core stabilization and balance training on dynamic balance. In our study we found significant difference within the group and we did not find any significance between the groups. This is in agreement with the study done by Kimberly et al. in 2005. They also specified in their study that, although the results of study between groups were not significant, enhancement of dynamic balance may result if the core stabilization training program is applied in the clinical settin.4
Zech A, et al in 2010 concluded that Balance training is effective at improving static postural sway and dynamic balance in both athletes and non-athletes. But balance training exercises should be given for longer duration for finding it to be effective.21

By just training the core, overall dynamic stability can be positively affected with strong magnitude of change. There is also evidence that a 4 week intervention might be enough to cause a significant training effect, with a strong magnitude of change in core global muscular endurance.6
Future research: In future, combined effect of core stability and balance training exercises on dynamic balance can be done. Study can be done on geriatric population. Bio feedback can also be incorporated in the study. Study can be done for longer duration.

INTRODUCTION
A wide spectrum of motor impairments affect function in children and adolescents which may be congenital and acquired conditions such as cerebral palsy, traumatic brain injury, myelomeningocele, spinal cord injury, Down Syndrome, and neuromuscular disease. Many of these disorders result from dysgenesis or injury to developing motor pathways in the cortex, basal ganglia, thalamus, cerebellum, brainstem, central white matter, or spinal cord. These conditions are associated with motor impairments including muscle weakness, abnormal muscle tone, decreased joint range of motion, and decreased balance and coordination. There are variations in severity within each of these conditions. Many children with impairments attributable to these conditions will have some degree of disability that may limit their normal development and functions and should benefit from physical,

ACKNOWLEDGEMENT
Brain damage causing cerebral palsy may develop during the prenatal, perinatal or postnatal periods. Prenatal factors have a significant role in the cases. Prenatal factors lead to premature birth and/or intrauterine retardation of the infant.11 This research showed that 29 (25%) of these deliveries were as a premature while 2 (2%) deliveries were as late deliveries. It is also found that factors related to central nervous system infection, metabolic, storage disorders, congenital, developmental disorders, hereditary, familial genetic and chromosome anomalies disorders included a several conditions with different rates that caused brain damage and retardation such as Kernicterus, Rett Syndrome, Mapple Syrup Urine disease, Cytomegalovirus infection, and Pelizaeus Merzbacher. Trauma, West syndrome and others unknown factors was recorded. In addition to the previous factrors of course the widespread prenatal, perinatal and postnatal factors such as pregnancy rsik factors, delivery risk factors, asphyxia, infections and injuries are common causes.12
impact of socioeconomic deprivation has been shown for many aspects of child mortality and morbidity but the relation between socioeconomic status and the risk of cerebral palsy is not clear. Low birth weight and prematurity are the strongest risk factors for cerebral palsy. Given the observed association between these factors and socioeconomic status, an increased prevalence of cerebral palsy with low socioeconomic status is expected. A strong association was observed between socioeconomic status and the risk of cerebral palsy.16 Other factors in child disability include poverty, lack of exercise, bad housing and poor diet are being

Effect of Postural Brace for Correcting Forward Shoulder Posture and Kyphosis in Patients with Chronic Obstructive Pulmonary Disease: A Pilot Study
Keywords: COPD, Posture, Kyphosis, Forward Shoulder Posture, Maximal Inspiratory Pressure
Results: All subjects tolerated the training load, improved their inspiratory muscle strength, and reported correction of posture.
ABSTRACT
Objectives: 1.To evaluate the effect of postural brace in correcting forward shoulder posture and kyphosis in patients with chronic obstructive pulmonary disease.( COPD)
Methods: Daily inspiratory muscle training(IMT) sessions of 30 minutes' duration and weekly training load increments of -2 to -4cmH2O over a 8-week period with the training device at loads of >30% of baseline maximal inspiratory pressure (PImax) was given. Posture was corrected by a brace and patients were asked to wear it throughout the day for 8 weeks.
Design: A Pilot study comparing baseline values with post-test values.
Subjects: A total of 30 subjects between age group of 45-60 years of either gender, diagnosed to have COPD with forward shoulder posture and Kyphosis were studied.
There is decreased strength and endurance of diaphragm in COPD.1,2 The inspiratory muscles are placed at a suboptimal length for generation of muscle tension due to overinflation.3 Hence the diaphragm is susceptible to fatigue as a result of increased loading and diminished “capacity” to produce inspiratory force.3,5,6 Inspiratory muscle strength and endurance have been shown to be reduced in COPD.4,7 Patients experiencing dyspnea in COPD benefit from IMT, as strong inspiratory muscles help decrease dyspnea.8 However the efficacy of IMT is controversial and its use in a clinical setting is limited in patients with COPD. Patients with COPD will attend forward head, rounded and elevated shoulders. Posture such as Kyphosis, and
forward shoulder posture (FSP) affects the respiratory values in COPD.1,11 There is excessive thoracic flexion in kyphosis and thoracic supportive device such as postural brace can be used to prevent excessive thoracic flexion, thus correcting posture. 14 Taking into consideration, the beneficial effects of IMT on strength of inspiratory muscles and the ill effects of bad posture in the form of dorsal Kyphosis and FSP on respiratory values in COPD, It is legitimate to question whether addition of postural correction with IMT has any beneficial effects in rehabilitation patients with COPD. Till date to our knowledge, none of the studies have reported weather IMT along with upper thoracic posture correction by a brace can have an additional effect on the strength of the inspiratory muscles in COPD. Hence the aim of this study was to evaluate the
Outcome measures: Posture was assessed by Plumbline (PL), intra scapular distance(ISD) and percentage of kyphotic index(KI). Inspiratory muscle strength was measured by deriving maximal inspiratory pressure (PIMax)
Conclusion: A combination of posture correction by a brace and inspiratory muscle training using TIMT is beneficial in improving posture and the strength of inspiratory muscles of COPD patients.
METHODOLOGY
Inspiratory muscle strength was derived as PI Max which was measured with a Magnehelic pressure gauge(No. 2000-200cm) at residual volume (RV) with the highest pressure generated in five trials taken as PIMax. Initially the subject was made to sit and asked to exhale slowly and completely (to RV). Then he/she was asked to seal the lips firmly around the mouthpiece (to prevent air leak), and then inhale forcefully through the mouthpiece (as if he/she is trying to “pull in hard, like you are trying to suck up a thick milkshake”). The largest negative pressure sustained for 1 second on the pressure gauge was recorded. The participant was allowed to rest for about 1 minute, and then repeated the maneuver 5 times. The highest value recorded, was taken for the study. The mechanical pressure gauge has minor tick marks at 5cmH2O increments, so results were rounded to the nearest 5cmH2O19,20
Intervention: Threshold inspiratory muscle training device (TIMT) was used to training the inspiratory muscles. Subjects inhaled through the spring-loaded TIMT device that provides resistance to inspiratory muscles. The pressure settings are adjustable in2cmH2O increments (range, -7cmH2O to-41cmH2O).The subjects were asked to inspire hard enough through the mouth piece to open the valve in the device and permit inspiration against that force. Nose clip were used to occlude nasal air flows. The initial training load

effect of adding postural correction to IMT in patients with COPD.
Subjects: 30 subjects between age group of 45-60 years of either gender, diagnosed to have COPD with FSP and Kyphosis, from Physiotherapy OPD of S.D.M. Hospital, were studied and taken as per their inclusion and exclusion criteria.
Thoracic length
KI (%)= Thoracic height X 100
Inclusion and exclusion criteria: Inclusion criteria: Subjects having mild to moderate COPD (as per GOLD standards) 9 with FSP and Kyphosis. Subjects were excluded if they had any respiratory conditions other then COPD, cardiovascular, neuromuscular, or orthopedic diseases. All the individuals with fixed deformities of shoulder girdle and upper quadrant were also excluded from the study.
between T3 spinous process and the vertebral border of both the scapulae was measured by an cloth inch tape. The distance was calculated in inches.15,16 Measurement of kyphotic index was done using a flex curve ruler of 60 cms. Initially, the subjects were asked to expose their spine and adopt their normal posture. C7 spinous process and posterior superior iliac spine(PSIS) level were marked.17 The flexicurve ruler was pressed against their back with the top end placed against the C7 spinous process in the midline. The ruler was molded into the shape of the subject’s spine in the midline to the level of the PSIS. The flexicurve ruler was removed and the shape of the spine was then traced on a paper consisting of the horizontal line.The cervical end of the flexi curve was placed on the line and the distal end of the ruler was made to coincide with the other end of the horizontal line .The curvatures were then traced on the paper. Thoracic height (H) and thoracic length (L) was measured. The KI (%) was calculated as18
Procedure: A routine method of evaluation and collecting data on COPD with FSP and kyphosis was done. Outcome measures such as Plumb line (PL), ISD (inter scapular distance) was assessed to know FSP. Kyphotic index(KI) was derived to know the percentage of kyposis and maximal inspiratory pressure (PI Max) was measured to know the strength of the inspiratory muscles. After briefing the subjects about the study, their written consent was taken and ethical clearance was obtained prior to the study. A plumb line was hung 3 feet in front of a wall with the plumb bob approximately a quarter inch off the floor anterior to the lateral mellolus. This point was considered as a reference point for assessing posture in lateral view. The subject’s were in bare feet, wearing clothing that allowed for visual observation of body landmarks and standing between the wall and the plumb line. Subjects were asked to expose the external auditory meatus. The tip of the acromian process was marked with a skin marker. The distance from the tip of the shoulder (acromion processes and is termed as “landmark”) and the plumb line was measured with a scale. For the purpose of analysis, FSP was graded as normal or mild that is considered to be within normal limits(WNL) or grade 1 and was measured from center of landmark in line with or up to 1cm anterior to the plumb line, moderate deviations or grade 2 was measured from posterior border of landmark in line with or displaced up to 1 cm anterior to the plumb line , and severe or grade 3 was measured from posterior border of bony landmark displaced more than 1 cm beyond the plumbline.13,15 For measuring ISD the subject was made to stand in his or her relaxed posture with back exposed .The horizontal distance

To determine inter-rater reliability, the measurements from all the outcome parameters obtained by rater 1 and rater 2 at baseline, 8weeks and 3 months were sub-jected to statistical analysis using Intraclass Correlation Coe-fficient type 3,1 (ICC3,1)21. To determine
Data analysis: All analyses were done using SPSS Ver-sion 16. Descriptive statistics are reported as means and SD (standard deviation). A repeated measures analysis of variance for each individual outcome measure time was performed to determine if there was any change in scores at three time periods. The repeated measures of time were baseline, 8 weeks post intervention and 3 months post intervention. The data sphericity was tested using the Mauchly test. When the test results were statistically significant, the data were corrected using the Greenhouse-Geisser correction to determine if significant differences existed between conditions. For significant main effects, pairwise comparisons were performed between levels using t tests with a modified Bonferroni procedure. Significance was set at p < 0.05.

As the strength improved to the point where subject were exercising for continuous of 30 minutes, then the pressure load was increased by2cmH2O. The advance in the pressure was up to, -40 cm H2O. TIMT was given with an intensity of 30% of PIMax for 30 min/ day for 8 weeks10

month follow up. Following intervention, both posture and inspiratory muscle strength improved in adult COPD patients after 8 weeks and the improvement was retained till 3 months of followup. Posture was corrected by a brace and correction of posture was associated with decrease in the intra scapular distance, kyphotic index and plumb line. IMT was given by a TIMT device and improvement in the inspiratory muscle strength was associated with increase in the maximal inspiratory pressure. Previous report 10 have demonstrated the use of TIMT device for training inspiratory muscles. IMT of 5 to 30 minutes’ for 6 weeks at loads of >30% of baseline PIMax improved patients’ inspiratory muscle strength, similar effects were found with 8 weeks of intervention and 3 months of follow up in this study (table 2).Poor posture along with weak back muscles, causes inability to straighten the upper back, which in turn limits the ability to raise and expand the chest and maximize the lung capacity.13

that correction of posture with brace, would have aided in straightening the upper back and expanding the chest, thus having an additional beneficial effect on inspiratory muscle force generated by the inspiratory muscles. Hence postural correction might have influenced the increase in the PIMax values along with inspiratory muscle training. In this study we found a high inter rater(ICC 3,1)and intra rater (ICC 1,1) reliability ( table 3,4) for all measurements to evaluate posture and strength of the inspiratory muscles in COPD patients.
The results of this pilot study suggest that, TIMT device can be used to improve the strength of the inspiratory muscles. With addition of postural correction by a brace, not only improved posture but also aided in increasing the inspiratory muscle strength. Hence, posture correction needs to be given adequate importance in pulmonary rehabilitation of patients with COPD, however, despite the lack of a control group and the small size of the sample studied, we suggest that further study is warranted.

Balance, both literally and figuratively, is one of the most important concepts and functions in life. Historically balance has not been considered a critical factor in rehabilitation of orthopedic patients or perhaps the impact of these deficits on high-level functional outcomes had not been sufficiently documented. Yet balance deficits in orthopedic patients exist are often persistent, impede the return of normal function and increase the risk of re-injury.1

Background: Poor postural performance is observed in patients suffering from neck pain and following Whiplash injuries. Fatigued muscles following the neck pathology are unable to transmit somatosensory information to the central nervous system, and hence upright postural control may be compromised. Hence there is need to investigate neck muscles fatigue and balance.
Effect of Neck Extensor Muscles Fatigue on Postural Control Using Balance Master
a highly integrative process involving multiple afferent pathways, depends on somatosensory,
The brain for the integration of this information and the formation of a motor plan and musculoskeletal system for the production of adequate movements to execute the plan. Problems in any of these areas can lead to the imbalance. The known presence of proprioceptive deficits and musculoskeletal impairments in orthopedic patients should arouse the suspicion that balance problem may exist in these patients and research confirms these suspicions.1,2,3,4 Poor postural performance is observed in patients suffering from neck pain and following whiplash injury in which there is hyperextension injury and too much rotation at the cervical spine.Especially those who have had injuries or disruption of joint surface in the peripheral joints or spine such as whiplash injuries to the neck. The small intrinsic, deep dorsal and suboccipital cervical muscles show a high density of muscle spindles that are likely to provide a main contribution to neck proprioception.
Conclusion: It is speculated that from the fatigued neck muscles, altered sensory input leading to abnormal central processing may compromise balance, thereby reflecting a notable change in postural sway.
The crucial role of the sensory systems and the brain in producing skilled, co-ordinated movement is recognized by orthopedic physical therapist as evidenced by closed chain testing and training.1, 2

OBJECTIVES
The four test conditions of modified CTSIB (m CTSIB) test administered each test for 10 seconds duration.
Neck pain or any type of musculoskeletal treatment taken for neck complaints in the past three months.
In the erect standing posture, the body undergoes a constant swaying motion called ‘postural sway’ or ‘sway envelope’. Physiological postural sway is defined as the continuous corrective movements around the center of gravity of a body designed to maintain postural control in the upright position while stand still.6, 7

If fatigued muscles are unable to transmit somatosensory information to the CNS, then upright postural control may be compromised. Therefore there is need to use a specific testing method to determine the correlation between the neck extensors fatigue and balance1, 5

Procedure for inducing fatigue in neck extensor muscles.
The subject assumed a supine position on the plinth with head and neck placed in neutral position such that tragus of the ear and tip of the shoulder are in the same horizontal plane. Layers of towels were placed under the head to achieve the neutral position as needed. The air bag of the stabilizer was folded into three and placed behind the neck suboccipitally. The airbag was inflated to 20 mmHg as baseline.
DISCUSSION
236 Indian Journal of Physiotherapy & Occupational Therapy. January-March 2013, Vol. 7, No. 1
As observed in this study, there was maximum increased postural sway in Eyes open, firm surface test condition, in spite of all the three sensory inputs were
available, which can be explained as because of neck muscles fatigue, the proprioceptors could not provide the accurate somatosensory inputs to the CNS, required for maintaining postural control and hence there was increase in postural sway. It can also be said that as this test was done immediately after the fatigue was induced hence the postural sway was maximum in this particular test condition as seen in graph 2.
In Eyes closed on firm surface, when the visual information was unavailable, the postural sway was increased and the difference between pre and post sway velocity was statistically significant as in this condition subjects relied more on somatosensory and vestibular inputs.Intest conditions on foam surface, there was additional challenge to musculoskeletal systems
TABLE -1 - Comparison of Postural sway velocities in four test conditions of mCTSIB pre and post neck extensors fatigue
Observation – Postural sway velocities before and after neck extensors fatigue were compared using the paired‘t’ test. There was significant difference between the Postural sway velocities demonstrated by subjects. In eyes open on firm surface the difference was highly significant (p value <0.001) whereas even though the postural sway velocities were high in eyes closed on foam surface the difference was significant. (p value <0.05). The difference between the postural sway velocities in composite of all test conditions was highly significant at p value <0.001.

So it can be inferred that mechanoreceptors of the synovial facet joints and surrounding soft tissues of the cervical spine if affected by a spinal injury such as whiplash injury or chronic neck pain due to cervical spondylosis can alter postural control. Stampley et al (2006) in their study, ‘Neck muscles fatigue and postural control in patients with whiplash injury’ showed that patients with whiplash injury show identifiable increase in neck muscle fatigability and associated increase in postural sway after contractions of dorsal neck muscles and physiotherapy treatment reduces these effects9

The submaximal isometric contraction of the neck extensor muscles for maximal no. of repetitions produced changes in displacement of center of gravity and velocity of postural sway in young healthy subjects. Therefore this study accepts the hypothesis that the neck extensor muscles fatigue significantly affects the balance, which was confirmed by mCTSIB test. Abnormal central processing of sensory input may compromise balance in the setting of postural perturbations to a greater degree in patients with neck muscles weakness as in case of chronic neck patients and whiplash injuries.

Introduction: Dance in its many forms has recently received much attention in medical literature and considerable promotion in the lay press. This has been in keeping with current awareness of physical fitness, which has been the result of increasing evidence linking cardiovascular disease to physical inactivity, lack of cardiopulmonary fitness and obesity.
Conclusion: The mean value of the vo2 max in ml/kg/min was found to be higher in Indian classical dancers than females engaged in gymnasium.
Less physical activity with relative sedentary life style habits leads to gradual deteriorations of physical wellbeing or even disability. Sports, exercise or everyday chores will help us to live longer.

Material and Methods: The study group consists of 30 female subjects aged 17-30 yrs from each group who had received training in their respective physical exercise/ activity for a minimum duration of 6 months. Aerobic power was determined by simple exercise step test (Queen's College step test). Grading of aerobic capacity was done by using indirect estimation of VO2 Max.
The number and percentage of females falling into good and average category was more in Indian classical dancers than females engaged in gymnasium. The percentage of Indian classical dancers from Bharatnatyam type falling into good category was more than Indian classical dancers from Kathak Thistype.
INTRODUCTION
It is common notion that only physical exercise provides physical fitness & is beneficial to health. But it is found that any type of physical activity done regularly can improve cardiovascular endurance. Indian classical dance is one of the physical activities as it is done regularly. The VO2 max in ml/kg/ml and aerobic capacity under grading into “good” and “average” category was more in Indian classical dancers than females engaged in gymnasium. Following are the reasons. a)Muscle group involved
The total muscle mass involved in Indian classical dance was much more and variable, moment to moment, in the entire duration of the activity in
MATERIALS AND METHOD
Cardiovascular endurance assessment by Queen’s college step test:
of VO2 max/ aerobic power in ml/kg/ min between Indian classical dancers & females engaged in gymnasium. The VO2 Max/ aerobic power in ml/kg/ min was to be higher in Indian classical dancers than females engaged in gymnasium. The difference was found to be highly significant with the ‘p’ value of 0.
Inclusion criteria
2)Subjects having any type of cardiopulmonary diseases like myocardial infraction, unstable angina, aortic stenosis, cardiac arrhythmia, acute endocarditis, myocarditis and pericarditis. Such subjects are excluded by history, general & systemic examination.

METHODOLOGY
Exclusion criteria
Observations & results
Prior to testing, required pretest instructions will be given & test was properly explained & demonstrated to each subject. Calculations were done to obtain the results.
The total number and percentage of females falling into “good” and “fair” category was more in Indian classical dancers compared to females engaged in gymnasium.Thetotal
number and percentage of females falling into “fair” category was more which was from study group of females engaged in gymnasium only.
Attempts have been made in the past to correlate other physical activities like ballet (western dance) with established physical exercise routines in gymnasium.1, 2. Indian classical dance is one of the physical activities as it is performed regularly. There are very few studies 3, 4, 5,6,7,8 showing that Indian classical dance (BharatNatayam, Kathak) can provide health related fitness and endurance.
The Table No. III show Comparison of actual & predicted vo2 max / aerobic power VO2 Max (ml/kg/ min) in females engaged in gymnasium. There was no difference in means of actual VO2 Max and predicted VO 2 Max. The difference was found to be nonsignificant with ‘p’ value of 0.05.
DISCUSSION
The Table No. IV show comparison of aerobic capacity/fitness in both study groups; Indian classical dancers and females engaged in gymnasium.
2)Minimum regular six months training (with at least one session of one & half to two hour’s duration & minimum three days in a week.)
The equipments used: Stepping bench of height 16.25 inches, Metronome set at 88 beats / min or 22 steps ups / min for women. Stop watch, Scale for measuring height, weighing scale.
Study was done in 2 groups
The Table No. II show Comparison of actual & predicted VO2 Max/ aerobic power (ml/kg/min) in Indian classical dancers. There was difference in means of actual VO2 Max & predicted VO2 Max. The difference was found to be significant with the ‘p’ value of 0.05.
Nritta – are rhythmical and repetitive elements, i.e. it is dance proper.
No threshold duration per workout exists for optimal aerobic improvement. If threshold exists, it probably depends on the interaction of total work accomplished (duration or training volume), exercise intensity, training frequency and initial fitness level. Generally, the more frequent and longer the endurance training programme is, the greater will be the fitness benefits10
CONCLUSION
Thus physical activity like Indian classical dance done regularly improved aerobic capacity/ cardiovascular endurance in dancers.
Natya (Abhinaya) – is the dramatic art, and is a language of gestures, poses and mime.
d)Effect of Kathak
e)Training period
Females engaged in gymnasium were performing exercises on treadmill, cross cycling and stepper with strength and flexibility exercises. Females engaged in gymnasium had speed, inclination variation while they were performing exercises on treadmill.
Indian classical dancers were practicing for an average duration of 45-60min daily. In addition, they were also learning the skills for 3-4 days in a week. This might be classified as intermittent type of training method. (Teacher teaches dance step for 5 min then student dances for learning that step for 5 to 10 min.)
Compared to Indian classical dancers, females engaged in gymnasium did the exercise for an average duration of 60 min. (15 to 20 minutes- treadmill, cross cycling, stepper; 30 min – strength and flexibility exercise.) females did this training for 5-6 days on an average in a week.
c)Effect of Nritta, specific position, Natya, Nritya and music in Bharatnatyam.
action. The solar plexus at the naval forms the centre from which all movements originate and are controlled by breath. The vibrations generated by Nritta lead to correction of energy imbalance in the body by acting upon nervous flexes or chakras a result of biochemical changes. Natya, Nritya and music were helpful in reducing the stress and increasing the functions of limbic system, reticular activating system, probably by releasing the neurotransmitters. This might help to elevate the mood and to keep the mind calm and alert.
comparison to females engaged in gymnasium. Predominantly the lower extremity is involved in the exercises performed by the females engaged in gymnasium. Thus higher the VO 2 Max in Indian classical dancers.
In Kathak physical activity is based on bhav (mood), raga (melody) and tala (rhythmic beat) mainly. Kathak dance is an art which has mainly vigor of dynamic foot work and pin point spins the subtle movements of the face and blended with miming of stories of all kinds. In Kathak workload was by “bells” around the ankles, leg exercise by tapping of feet in a high speed rhythm called “Tatkar”. Kathak dance improves and maintains cardiovascular endurance and respiratory fitness.
f)Goal
The goal of most of the Indian classical dancers is to attain expertise in a dance form, some of them wanted to make career in dance and few of them were dancing as a hobby. But the goal of the females engaged in gymnasium was to reduce weight to maintain figure, while some of them wanted to achieve for physical fitness.
Training period varies among dancers & among females engaged in gymnasium.
b)Duration
Nritya – is a combination of Nritta and Natya.
Bharatnatyam comprises three aspects, Nritta, Nritya and Natya.
Nritta in Bharatnatyam type includes complex steps in different postures with expressions which involve each and every part of the body of the dancer. In Nritta the whole body was made the instrument to produce
.This concludes that the VO2 max in ml/kg/ml and aerobic capacity under grading into “good” and “average” category was more in Indian classical dancers than females engaged in gymnasium.

The organism (inclusive heart) could tolerate a prolongation of the exercise period when larger mass of skeletal muscle were activated. The subjective feeling of strain was more related to metabolism. Therefore a training of the oxygen transporting system was more efficient and psychologically less strenuous, the larger the muscular mass involved in dynamic activities. 9

ABSTRACT
Conclusions: We concluded that there is significant reduction in grip strength in diabetic group. It was increased as the duration of diabeties was increased. There fore incorporating grip strength evaluation and treatment at the earlier stages may help in preventing complication, which will also reduce the impact on functional disability in diabetic population.

Diabetes causes various system dysfunction and which leads to disabling function which include musculoskeletal disorder although other complication of diabetes are better recognized as cause of the morbidity and mortality. The musculoskeletal syndromes associated it with it may be very debilitating.3Theprevalence of connective tissue disorder in these patient has increased in the recent years affecting significantly their quality of life. Approximately 82.6% of individual with diabetes have been found to exhibit musculoskeletal abnormalities, mainly of the degenerative, non-inflammatory type musculoskeletal disorder are the common finding among patient with type –II diabetes. It causes connective tissue in many ways which leads to different alteration in periarticular and skelectur system.4

PROCEDURE
Before testing vitals were noted and the procedure was explained and demonstrated in local language. The position prescribed by the American Society of Hand Therapist was used. The dynamometer reading taken was mean was three trials for each hand. The dynamometer was reset to zero prior to each reading and was read to be nearest increment of the 2 scale division. 60 second rest was given between each trial. Each contraction was held for 3 seconds. 11
The study was approved by the SDM College of Medical Science & Hospital Ethical committee. Subjects with diabetics mellitus were screened by doing routine blood test and previous record which followed to the Principal Investigator. Grip strength was collected using Hand Dynamometer9,10. Inter- rater and intra –rater reliability were assessed by a pilot study and ‘r’ values were found to be 0.95 and 0.94 respectively.

DISCUSSION
Hand is an important target for diabetic musculoskeletal complication. Much less attention has been given to the hand. Hand function is crucical for productivity and quality of life.12,13 The mean BMI was 25.18 kg/m2 in diabetic and 25.69 kg/m2 in non diabetic thus no significant difference was found. As BMI (Body Mass Index) said to influence grip strength. That is individual with higher BMI has higher grip strength.
FUTURE SCOPE
Work profile /level of physical activity were not taken into considerations
Also reduction in grip strength is associated with power glycemic control with increased systemic inflammatory cytokines such as Tumor Necrosis Factor á (TNF-á) and interleukin-6(IL-6) have detrimental effects on muscle function. Distal symmetrical neuropathy which may present sebclinically is also responsible for distal muscle weakness and therefore attributes to low grip strength15.

Design: Cross sectional study
Methods: Beighton score was used to evaluate 420 healthy children. One point was scored for each positive result (maximum: 9). Scores >4 were considered to be generalised hypermobility. Body mass index was calculated using height and weight of the children. Then, the data was evaluated statistically using SPSS 16.0 version statistical software and results were obtained.
Objectives: Joint hypermobility indicates an increase in the range of joint movement among normal individuals. Joint hypermobility commonly occurs in school age children (8-39%). Weight gain may precipitate the onset of symptoms of hypermobility syndrome. This study was done to assess the correlation between hypermobility and body mass index in children aged 6-12 years.
Conclusion: Hypermobility was more prevalent (57.14%) among under weight children aged 6-12 years.

INTRODUCTION
There is no study done on correlation between hypermobility and body mass index in children aged 6-12 years. There is need for identifying body mass index in hypermobile children who are at risk of developing musculoskeletal complications. Education and therapeutic interventions can be targeted to this specific group of children before they become symptomatic and prevent further sequelae.
The most widely used scale for hypermobility is the Beighton hypermobility score. It can be conducted easily and requires less time. A study done by van der Giessen LJ showed that Beighton score is valid in healthy children aged between 4 to 12 years.4 It is a practical and reliable method for defining hypermobility in children.

Study of Correlation between Hypermobility and Body Mass Index in Children aged 6-12 Years
In this study we assessed the correlation between hypermobility and body mass index in children aged 6–12 years.
Results: The result showed that 57.14% of hypermobile children were under weight, 35.93% of hypermobile children had normal weight, 19.15% of hypermobile children were at risk of being overweight where as 16.67% of hypermobile children were overweight. A negative correlation (-0.0008) between hyper mobility and BMI was found.
Ancedontal evidence suggests that sudden and substantial weight gain may precipitate the onset of symptoms, notably arthralgia, in previously asyptomatic hypermobile individuals. Despite the fact that no study has yet demonstrated an improvement in symptoms following weight loss, it would seem advisable to recommend such a measure to obese adults or children with the symptoms.5
Generalised joint hypermobility indicates an increased range of motion in general compared with the mean range of motion. Generalised joint hypermobility is claimed to be present in 5–15% of general population.1 There is clear evidence that factors such as gender, age group, ethnic group, certain physical activities and their intensity, and the presence of certain pathological conditions, may be associated with joint mobility.2 Greater range of motion is inherently present in children than adults.3
ABSTRACT
using Beighton score. One point was scored for each positive result (for each side), and scores of 4 or more points were considered to be generalised hypermobility. The children were categorized according to the scoring.

METHOD
Before commencement of the study, an ethical clearance from Shri Dharmastala Manjunatheshwara Institutional Ethical Committee, Dharwad was taken. Children from various schools of Dharwad were included in the study. Prior to the commencement of the study, a written consent letter was obtained from all parents.
248 Indian Journal of Physiotherapy & Occupational Therapy. January-March 2013, Vol. 7, No. 1
Joint hypermobility was measured in five body areas
420 children aged 6–12 years were included, of which there were 252 boys and 168 girls. At first, all the children were screened by a paediatrician and children with skeletal problems such as fracture, neuromuscular disorder like cerebral palsy, rheumatic disorders, metabolic dysfunctions or disorders such as homocystinuria, developmental delay and genetic disorders such as downs syndrome were excluded.
At risk of being overweight38 80.85919.15 4711.19
Along with scoring the hypermobility, even height and weight of the children were taken. Body mass index (kg/mt2) was calculated using these height and weight measurements. According to CDC growth charts, the children were categorized as underweight, normal weight, at risk of being overweight and overweight groups.
Table1 shows the distribution of study subjects with respect to BMI and hyper mobility. This table shows that 57.14% of hypermobile children were under weight, 35.93% of hypermobile children had normal weight, 19.15% of hypermobile children were at risk of being overweight where as 16.67% of hypermobile children were overweight.
Table 2 shows correlation between hyper mobility scores (i.e. only scores are greater than or equal to 4)
SPSS 16.0 version statistical software was used for statistical analysis. The investigator used Chi square test to evaluate the descriptive statistics that is distribution of study subjects by BMI and generalised hypermobility. Then, the Correlation between hyper mobility scores (i.e. only scores are greater than or equal to 4) with BMI scores was found out using Karl Pearson’s correlation method.

The limitations to our study was that further follow up regarding any complication secondary to generalised hypermobility was not carried out. Moreover, hypermobile children were screened subjectively and individual hypermobility were not documented (example, elbow hyperextension). No correlation between socioeconomic factor and hypermobility was studied.

A population-based evaluation of generalized joint laxity (Hypermobility) in fourteen-year-old children from the UK was studied. Among the 6,022 children evaluated, the prevalence of hypermobility (defined as a Beighton score of >4 [i.e., >4 joints affected]) in girls and boys age 13.8 years was 27.5% and 10.6%, respectively. 45% of girls and 29% of boys had hypermobile fingers. There was a suggestion of a positive association between hypermobility in girls and variables including physical activity, body mass index, and maternal education. Girls who were obese were 2.7 times more likely to be hypermobile (adjusted OR 2.70 [95% CI 1.24–5.88]) compared to girls who were underweight.7Ourstudy
Future scope of this study will be long term follow up of any secondary problem in hypermobile group of various body mass index.
A study was done to know the prevalence of joint hypermobility in children from Mumbai, India and its association with malnutrition. 829 children of the lower urban socio-economic strata, between 3 and 19 years of age were evaluated independently by two observers for hypermobility using the Beighton 9-point scoring system. Their nutritional status was stratified using standard Indian growth charts and hypermobility was quantified in various nutritional groups. Musculoskeletal symptoms were assessed by a questionnaire given to parents. They found hypermobility in 58.7% of population. Near equal sex incidence was noted. A higher incidence of finger signs was noted in comparison to elbow hyperextension, knee hyperextension and hands to floor. 26% of the hypermobile population had musculoskeletal symptoms as compared with 17.2% of the non hypermobile population. A positive Beighton score was found in children with grade 3 and 4 malnutrition and 26.1% of those hypermobile had musculoskeletal to symptoms in comparison 17.7% of their non hypermobile counterparts.6

Comparison of Reaction Time in Older Versus Middle-aged Type II Diabetic Patients - An observational Study
Introduction: Diabetes mellitus affects the various systems of the body like the somatosensory, auditory system and slows psychomotor and cognitive responses all of which together may affect the reaction time. Reaction time is the time taken by the individual to react or respond to a applied stimuli. Slowing of these reaction times affects the everyday tasks such as balance, increasing probability of a slip or a fall.
Diabetes mellitus a metabolic disorder of multiple aetiology. It is characterized by chronic hyperglycaemia associated with disturbances of carbohydrate, fat and protein metabolism. This may result due to defect in the production of insulin or its action or due to both the mechanism. 1 India ranks first in the list of top 10 countries estimated to have the highest numbers of people with diabetes in 2000 and 2030. 2 The International Diabetes Federation (IDF) estimates the total number of people in India with diabetes to be around 50.8 million in 2010, rising to 87.0 million by 2030.3 Diabetes mellitus may present with characteristic symptoms such as thirst, increased frequency of urination, visual disturbances, and decrease in body mass. The condition is symptomless in initial stages but may give rise to various complications affecting various organs of the body like eyes, kidneys, nerves giving rise to conditions like retinopathy, nephropathy, and neuropathies respectively. Diabetes also affects the

Results: Results showed that the reaction time in Group A was 0.19 seconds (±0.01) and in group B it was 0.21 seconds (±0.01). The reaction time was more in group B compared to group A but was not statistically significant. The co-relation co-efficient between age and reaction time of the two groups combined was r=0.605
central nervous system and Type 2 diabetes has been associated with cognitive impairments4
Reaction time is the time taken by an individual to react or respond to an applied stimulus. It is the time lapse between the stimuli and response shown by the individual. Reaction time is considered to be a putative component of higher cognitive functions 5 this reaction time is found to be increased in individuals with type II diabetes 6. The reaction time depends on both the peripheral and central components of the nervous system. Impaired peripheral sensations and declined cognitive function, due to affection of central nervous system are the important factors for increased reaction times in diabetic individuals. One of the largest implications of increased reaction time is in the area of slips and falls. Falls are incurred by most of the diabetic population and are a common source of morbidity and mortality. Hence the assessment and improvement of reaction time constitutes an important part of management of individuals with type II diabetes.

Various studies are done to assess the reaction time in diabetic individuals by comparing with the healthy individuals but no study is done on comparison of these reaction times between patients with diabetes mellitus of different age group. Hence objective of this study was to compare the reaction time in middle age and old age type II diabetic patients.
PROCEDURE
The participants were explained about the test to be performed and written consent was obtained from each participant. After obtaining the consent the patient was allotted to one of the groups according to his/her age. The reaction time in all subjects was tested using the Drop Ruler Test.7 A 30cm wooden ruler was used to perform the test. The subject was made to sit on a chair or stool with elbow supported on a table with wrist outside the table. The forearm was placed in midprone position. The ruler was then placed between the thumb and the index finger such that the finger and thumb are close but not touching the ruler. The 0cm mark on the ruler coincided with the borders of the fingers. The ruler was then dropped between two fingers without prior intimation and the subjects were asked to grasp it at their earliest. The distance at which the ruler was grasped was noted down and reaction time was calculated. The standard equation for freely falling bodies is Sf=1/2at2+vot+So.8 Where Sf is the average distance that the ruler fell, a is the acceleration of gravity (980 cm/sec2),t is the time that it takes the ruler to fall (the reaction time), vo is the initial velocity (zero) and
30 subjects diagnosed with type II diabetes from KLE’s Dr. Prabhakar Kore Hospital And Medical Reasearch Centre, Belgaum and Vrudhashram were recruited in this study and divided in to two groups according to their age. Those between age 40 to 60 were allotted to group A and those between age 60 to 80 were allotted to group B. Group A had 15 patients (9 females and 6 males with mean age 50.4 yrs +/- 6.16 yrs) and Group B also had 15 patients (7 females and 8 males with mean age 70.2 +/- 4.73 yrs).
Mean baseline demographic values were calculated for the continuous variables and analysis was done to find the co-relation between age and the reaction time. The data was analysed in SPSS 16 using independent t-test to estimate the difference between groups in each outcome. The significance level was set at p<0.05.
PARTICIPANTS
As the intra subject variability is high in this method 10 trials were conducted for each subject and the mean reaction time was taken for statistical analysis.
RESULT
Statistical analysis
So is the initial distance (zero). Substituting in zero for vo and So simplifies the equation as Sf=1/2at2. Solving this equation for t yields dt=√(2Sf/a)
The data were collected from group A and group B which was analysed and assessed for the significance. (Table-1) The gender distributions among the groups were as follows; in group A there were 6 males and 9 females with mean age 50.4 (+/-6.16) years and in group B 8 males and 7 females with mean age 70.2 years (+/4.73) were included. The mean height of group A was 1.65 meter (+/-0.14) and group B the mean height was 1.61 meters (+/-0.13). Hence there were no significant difference between the groups and within the group as far as height was concerned. The weight of participants of group A was 65.21kg (+/- 4.17) whereas in group B it was 65 kg (+/- 11.02). Within the group there were moderate difference whereas inter group comparison does not show any significant difference hence it may be concluded that the group was homogenous. BMI was assessed and for group A mean BMI were 23.62 (+/2.38) thus signifies that there were hardly any overweight individuals included in group A. In group B mean BMI was 25.03(+/- 1.98) suggestive of presence of overweight individuals in this group. The reaction time was calculated in group A and found that mean reaction time was 0.19 seconds (+/- 0.01) and in group B 0.21 seconds (+/- 0.01). The reaction time of groups might be related to the BMI of the groups. The co-relation co-efficient between age and reaction time of the two groups combined is r=0.605

A reaction time measurement includes the latency in the sensory neural code traversing peripheral and central pathways; perceptive, cognitive and volitional processing; a motor signal again traversing both central and peripheral neuronal structures; and finally, the latency in end effector (e.g., muscle) activation5. Many studies have been done to evaluate the reaction times in healthy individuals. A study on human reaction times found that in almost every age group, males have faster reaction times than females and also that while men were faster than women at aiming at a target, the women were more accurate.9 Here in the present study the difference of reaction times in females and males with diabetes was not calculated. A longitudinal study was done on 1,265 community-dwelling volunteers (833 males and 432 females) who ranged in age from 17 to 96 and cross-sectional analyses revealed slowing of simple reaction (SRT) and relatively greater slowing of disjunctive reaction time (DRT) across decades for both males and females. Repeated testing within participants over eight years showed consistent slowing and increased variability with age 10. In our study similar results were shown with group B having more reaction time compared to group A. Holmes et al. reported significant slowing of visual reaction time during a hospital clamp study at a blood glucose level of 16.7 mmol/l but were unable to replicate this subsequently using an auditory reaction-time task.11 The present study showed that hyperglycaemia is associated with increase in reaction time in diabetic individuals. There is increasing evidence that hypoglycaemic episodes are also critical factor in type 2 diabetes and older subjects aged more than 65 years, who represent the majority of type 2 diabetic patients, appear at a particularly high risk of experiencing severe hypoglycaemia. Hypoglycaemia unawareness in the presence of pronounced hypoglycaemia, induced reaction time prolongation in older type 2 diabetic patients 12 . Earlier study on diabetic individuals concluded that middle-aged individuals with type 2 diabetes showed a greater decline in cognitive function than middle-aged individuals without diabetes 3 . Another study on the effect of metabolic syndrome on cognitive function showed that subjects with metabolic syndrome showed poorer cognitive performance than subjects without metabolic syndrome, especially those with high levels of inflammation and hyperglycaemia was the main contributor of the association of metabolic

CONCLUSION
The further scope of this study is to evaluate large population of diabetic individuals and to take into account the duration of the condition which was not considered in the present study.
In the present study there is increase in the reaction time in the second group but is not statistically significant. This increase may be due to age factor or episodes of severe hyperglycaemia. Another reason may be the increased BMI in the second group i.e group B. study on middle aged individuals concluded that increased BMI was associated with poor cognitive functions15. Comparison of type 2 diabetic subjects with normal individuals concluded that patients with long standing diabetes showed improved cognitive capacity with restoration of glycaemic control16. Hence it can be said that the decline in cognitive function in diabetes mellitus is rapid in the first few years after diagnosis and with progression of the condition the process of this decline is slowed down. This might be a reason why there was no significant difference in the reaction times between the middle aged and old aged diabetic individuals. The reaction time in Group B did not show statistical increase because the increased reaction time in them may be attributed to the old age more than presence of the condition.
Our present study concludes that the slowing of reaction time in individuals with type II diabetes is more pronounced in the early stages of the condition and does not significantly worsen with the progression of the disease.
syndrome with cognition 13 . Study done on 20 individuals with type 2 diabetes with mean age 61.5 years concluded that during acute hyperglycaemia, cognitive function was impaired and mood state also deteriorated.14 These evidences show that the delay in the reaction time may be the consequence of somatosensory affection, cognitive decline and hypoglycaemic unawareness.

Sensory symptoms in autism also are impacted by cognitive maturation, at least in preschool-aged children. Researchers have found that lower mental ages are predictive of aberrant sensory features in young children with autism or other developmental disabilities9. Based on the previous studies there was a relationship between executive functions and sensory processing disorder in individuals with ASD, virtually
Sensory processing disorder (SPD) is quite common among children with autism; literature reports a range of occurrence from 42% to 80% 1. Children with evidence of sensory processing dysfunction, such as those with autism, often have difficulty regulating their response to sensation and specific stimuli and may use selfstimulation to compensate for their limited sensory input or to avoid overstimulation 2. These atypical sensory reactions suggest poor sensory integration in the central nervous system and could explain impairments in attention and arousal1.

INTRODUCTION
Despite the documented deficits in working memory (WM) in autism, relatively little research has been published on procedures for remediating these deficits. A small number of studies have evaluated approaches to improving working memory, often focusing on children with attention deficit hyperactive disorder (ADHD), fetal alcohol spectrum disorder (FASD) or Down syndrome. The rehearsal training program effectively improved the mnemonic performance of a child with down syndrome7. This finding was later replicated with typically developing peers. For example, authors found that WM span scores increased as a result of using a rehearsal strategy and positive reinforcement improves the WM in autism8

memory) intervention also could account for the improvement of sensory issues in autism. This will allow researchers to determine whether working memory intervention will solve the sensory processing disorder in children with ASD.
This pilot study investigated the effect of rehearsal digit span WM training on Sensory processing disorder (SPD). Twenty children's with autism (6-9 years) were participated. The experimental group received combination modalities of rehearsal digit span WM training to SPD, while the control group did not receive. The duration of training was one hour, twice per day for ten sessions. The finding indicate that rehearsal digit Span WM intervention has significant changes in the auditory filtering and no changes in tactile sensitivity, movement sensitivity, low energy, visual/auditory sensitivity taste/smell sensitivity, seeks sensation and total score, since training was not conducted with controls. The study discusses consideration for future WM intervention on SPD for children with ASD.
One area of executive function (EF) is which is frequently discussed in autism is working memory (WM). Among the many potential areas of deficit in autism is related with executive function3. The clinical presentation of sensory processing disorder in autism has been linked to deficits in executive functioning5. Executive function is an umbrella term for a set of subfunctions that are integrated throughout cortical and subcortical areas of the brain and used to carry out higher order cognitive tasks. Overall the evidence is mixed about the relationship between sensory processing disorder and executive deficits in autism, and it is unlikely that executive dysfunction is the primary explanatory model of these behaviors4. Still it is important to examine if executive function (working

The four digit recall tasks were designed using the different combinations of visual and auditory modalities for both the input presentation and the child’s response (output), as described in Table 2. All four tasks used digit sequences, which ranged from two to seven digits. In order to minimize the use of a chunking strategy, sequences did not include repeated or consecutive numbers. The four task types were used for both the DF and DB recall conditions. The digit recall tasks are available on the journal’s website at (http:// www.informaworld.com/ijslp).

Table 3. Pre and post test scores for all participants on the SSP for both groups
Prior to each task, the participants were given a short explanation outlining what they were required to do and some reminders. The tasks that used visual input or required gestural output included a 3-second presentation of the full digit grid before the task began, to familiarize the participants with the designated locations of the numbers. Each task began with four training items (two trials at a length of two digits and two trials at a length of three digits). This allowed the participants to become familiar with the demands of the task and receive feedback if they were a difficulty. The test sequences began at a length of two digits and progressed to a length of seven digits, with two trials at each length. The participant was required to score at least one of the two trials correct at each digit length to progress to a longer sequence. This design was adapted from Pickering.15. For each digit sequence, the tester controlled when it was presented and said ‘‘go’’ after its completion. The participants then gave a response and the tester recorded this online. A 3-second animation reward was then revealed on the screen.

The tasks for both the DF and DB conditions were presented in the following order: Task 1 (Aud/Verb), 2 (Aud/Verb-Mot), 4 (Aud-Vis/Verb-Mot), 3 (Aud- Vis/ Verb). Tasks with auditory only input were presented first, followed by those with mixed modality input. The DF and DB tasks were completed in separate sessions, with the DF tasks first and the DB tasks in the last session. Before starting the DF condition, each child was shown a full digit grid and asked to name the numbers. The tester pointed to each number in a random order to ensure automatic speech patterns were not used. If the child unable to recognize and name one or more of the numbers, they were excluded from further testing. Production of a correct sequence was given a score of 1, and a sequence where any number was incorrect was scored 0. If there was a discrepancy between the number the child pointed to and the number said aloud (regardless of whether one of these was correct), a score of zero was given for that sequence.

changes in the experimental and control groups were found in the scores on the SSP or from pretest to posttest. Many reasons could exist for the non significant results, ranging from a lack of rehearsal working memory and sensory memory training. With regard to the effectiveness of intervention, it may not fully reflect common clinical sensory processing disorder because recommendations for rehearsal into other working memory span were not provided.

To fully interpret and apply the results of this study, several limitations should be considered. As with pretest–posttest control group designs, a small sample was used; we had only twenty participants. Conclusions from the study should be interpreted and applied in the context of the small number of participating individuals. To increase external validity and generalizability of results, future researchers should include a larger sample size. Second, this study involved digit span task only as intervention and duration of treatment was short. Working memory involved many tasks such as listening recall, counting recall, word list matching, word list recall, Non-word list recall and others. Future researches to need to be examined all the combined tasks of activities to WM skills on sensory processing disorder. Third, this study was not used sensitive of outcome measures for sensory processing disorder in ASD.

Children who not receive some specific training they do not show any significant changes in their performance. In addition, the sensitivity of the measurement tools may have influenced their ability to detect the changes.

Results identified significant post-intervention changes in auditory filtering (see Table 4) between the groups, as determined by SPP scores in the area of sensory processing. The findings of this study show that auditory short-term memory performance can be improved in children with ASD through rehearsal strategies. Previous study suggested that since shortterm memory skills are strongly related to language acquisition, it is very important to improve these skills in children with ASD17. The rehearsal working memory intervention improved auditory filtering in experimental group. In this study, an experimental group applied rehearsal training on working memory with animation reward in children with autism. A reward is one type of positive reinforcement. Positive reinforcement provided motivation to the respondent to perform the digit span tasks. Researcher suggested that basic intervention (positive reinforcement) may be successful in improving working memory in children with

Evaluation of Inter-Rater Reliability to Measure Hand and Arm Function in Reaching Performance Scale for Stroke Patients
INTRODUCTION
Stroke is the third leading killer on western countries after heart disease and cancer. Among all neurological disease of adult life, the cerebro-vascular disease ranks first in frequency and importance. 1 Stroke or cerebro-vascular accident CVA is defined as a rapidly developing clinical sign of focal or global disturbance of cerebral function lasting for more than 24 hours or
Indian Journal of Physiotherapy & Occupational Therapy. January-March 2013, Vol. 7, No. 1 259
Procedure: The patients were examined by two Physiotherapists respectively. The patient was seated in a chair with backrest but no arm rest. Reaching performance scale evaluated six components. For all patients both close target [Task I] and Far target [Task II] were assessed and graded. Only reach to grasp component of task are taken into account. The inter-rater reliability to measure the hand and arm function in Reaching Performance scale was statistically analysed by the Mann-Whitney test with P<0.05.
Introduction: Stroke is defined as a rapidly developing clinical sign of focal or global disturbance of cerebral function lasting for more than 24 hours or leading to death due to no other reason than vascular origin. As there is high incidence of middle cerebral artery stroke, upper limb is more affected than the lower extremity and about 20% of the individual fail to regain any functional use of affected upper extremity. When a stroke patient attempts to move and encounters all the deficits the natural reaction is to compensate with available motor strategies. The measurement of the performance of the affected arm and hand of the patient with hemiplegia is important for determining the goal of intervention as well as outcomes of rehabilitation. So there is a need to have a scale that measures the quality of motor performances specific to the task and identify which elements of the task are missing and how they are compensated. Reaching performance scale is for the identification and quantification of movement pattern and their compensation during reach to grasp task in patients with upper extremity involvement after a stroke.
Result & Conclusion: In this study the reliability between the investigators is very highly significant correlation of closed target (0.951) and P <0.05, Far target (0.946) and P<0.05. So we can conclude that inter rater reliability of RPS scale in assessing arm and hand function is high and hence RPS can also be used to assess the compensatory strategies in stroke patients for an effective intervention.

Materials & Methodology: 30 Hemiplegic patients between age group of 40-60 years who met the inclusion criteria were selected and explained about the study and procedure, and the consent for the study was taken. The Type of study is Inter-rater reliability study (correlation). The Materials used were card board cone, Table, inch tape and a chair.
The measurement of the performance of the affected arm and hand of the patient with hemiplegia is important for determining the goal of intervention as well as outcomes of rehabilitation.13 Functional outcome scale access the performance of daily living at the activity level and quantify whether task is performed with in the constraint specified by the test, while little attention is paid how the movement performed. Impairment scales assess the underlying impairment such as decreased range of motion or muscle weakness or how well the specific movement performs. Thus test evaluate movement or movement pattern having no
functional goal. Impairment scales identify the factor that may affect the performance of the task.14 So there is a need to have a scale that measures the quality of motor performances specific to the task and identify which elements of the task are missing and how they are compensated.15 Reaching performance scale is for the identification and quantification of movement pattern and their compensation during reach to grasp task in patients with upper extremity involvement after a stroke. These scales particularly focus on the transport phase of reaching, defined as the beginning of the movement until the object is grasped. This scale also includes a measure of compensatory strategies used for grasping.
METHODOLOGY

The most common insult to the brain results from middle cerebral artery lesion. More than two third are within the distribution of middle cerebral artery5. Owing to high incidence of middle cerebral artery strokes, upper limb is more affected than the lower extremity, about 20% of the individual fail to regain any functional use of affected upper extremity. Typically distal muscles more affected than proximal muscles.6 Grip strength changes accordingly to the size of object being grasped. In hemiplegics commonly grasp an object and then initiate the movement from the shoulder which places the hand in a non functional position 7 . Recent movement analysis studies shows that the patient with hemiparesis due to stroke, use excessive trunk and shoulder girdle displacement, when pointing to targets or attempting to reach and grasp objects placed within and beyond the reach of the arm 8. Such excessive displacement is thought to be compensatory behaviour emerging from the efforts of spared cortical and subcortical system to compensate for lost control over motor function such as elbow extension and shoulder elbow inter joint co-ordination.9
As the test procedure is to find the inter-rater reliability, the patients are been examined by two Physiotherapists respectively. Prior to performance, the patient were been instructed briefly how to carry out the test procedure. The patient was seated in a chair with backrest but no arm rest. The chair kept facing the table. The table and chair placed one arm distance of patients arm, keeping wrist on the table. Patient seated without leaning on the back support and patient feet flat on the floor. A card board cone kept on the table. Reaching performance scale evaluates six components
in south India, the incidence of stroke is 56.9 per 1, 00,000 population.4
PROCEDURE
The purpose of the study is to assess the inter-rater reliability of Reaching Performance Scale test in hand function evaluation. 30 Hemiplegic patients between age group of 40-60years who met the inclusion criterias were selected by simple random sampling from various hospitals and rehabilitation centers. They were explained about the study and procedure, and the consent for the study was taken. The Inclusion Criteria include patients who Sustained with single Cerebro vascular accident, aged between 40-60 years, with duration of one month to five years, having good cognitive function, both the right and left side involvement. The Exclusion criterias were Patients who are not able to follow simple instructions, having any musculoskeletal condition that prevent test procedure, Non co-operative patients, flaccid stage and Mental retardation. The Type of study is Interater reliability study (correlation). The Materials used were card board cone [7 cms base & 17.5 cms height] , Table [72 cm height], inch tape and a chair [seat height 42 cms] to evaluate hand and arm function by using Reaching Performance Scale.
Studies of motor recovery following stroke have shown that improvement in outcome measures such as speed, precision and variability of arm movement may be accomplished by compensatory strategies. For example in patients with severe hemiparesis, compensatory trunk movements that are used to extends the reach of the arm may limit the recovery of shoulder adduction and elbow extension needed for independent arm movement.10 A compensatory strategy used by stroke patients is the fixation of body segments. This may decrease the number of motor elements (degree of freedom).11 A negative consequence may be the lack of girdle mobility, which may limit the normal kinematics of upper and lower limb movement.12

RESULTS
This study was aimed at determining the inter rater reliability of Reaching performance scale test in assessing the arm and hand functions of stroke patients. The data analysis and statistical inference has reinforced the reliability of Reaching performance scale test. This study indicates reaching performance scale test is extremely reliable for each of the subscales as well as the total score when performed by different raters. Different users of RPS test achieved consistent

result.

Reaching performance scale test is constructed for assessing upper limb functional recovery. Performance evaluated for close and far targets. A wide range varying from acute stroke to chronic strokes were included in this study. The duration of the samples
included ranged from a minimum of 1 month to 5 years of post stroke. Mindy F Levin concluded that the interrater reliability of reaching performance scale in assessing arm and hand function was significantly high.17Inthis
This study led to the inference that the Reaching performance scale test used in assessment of hand function in stroke patient has got very high significant inter-rater reliability. The current study being an evaluative study, have assessed the functional recovery of affected upper limb, and the inter-rater reliability, so that it can be used for clinical and research purpose. The inter-rater reliability is found to be high, the clinical implication of this study is that this scale can be used either when two therapists treat the same patient or when the clinical data is shared and they will be able to interpret each other score without assessing the patient again. Though the inter-rater reliability of Reaching performance scale test was already proved but it was less compared with that of intra rater reliability and further studies was recommended.
To mask the impairment the patient always compensate with the other movement to accomplish the task. For example a patient with severe hemiparesis, compensatory trunk movements are used to extend the reach of the arm. This may limit the recovery of shoulder adduction and elbow extension needed for independent arm movement. Compensatory strategies in reaching activities of stroke patients are adaptive one. It invariably lead to other problems by causing altered movement or joint glides. Hence it is important for then to be evaluated and corrected. This scale particularly focuses on transport phase of reaching i.e. the beginning of movement until the object is grasped. This scale also includes measure of compensatory strategies used for grasping.

study the reliability between the investigators is very highly significant correlation of closed target (0.951) and P <0.05, Far target (0.946) and P<0.05. So we can conclude that inter rater reliability of RPS scale in assessing arm and hand function is high and hence RPS can also be used to assess the compensatory strategies in stroke patients for an effective intervention.
To conclude, the inter-rater reliability of Reaching performance scale test was analyzed and found that it is highly reliable, with high level correlation and significance in measuring hand function of stroke patients.
In the flaccid extremity as a result of CVA there is insufficient muscle tone to hold the glenohumeral joint in proper alignment due to the force of gravity and weight of the arm. The scapula placed in a downwardly rotated and abducted position (Ryerson and Levitt 1997). In the extremity with the spasticity unbalanced muscle activation can contribute to downward depression and retraction of scapula (O‘ Sullivan 2001). Difficulty with Reach, and grasp occurs often in the patient with CVA. The factors that may cause changes in upper extremity function are unbalanced muscle pull, paralysis, decrease in sensation, secondary joint changes, pain and odema. These factors restrict the reach and grasp due to increase tone of muscle, the pattern that develops include internal rotation and elevation of shoulder, elbow flexion, fore arm supination or pronation, wrist and finger flexion. If this position of fingers and wrist flexion continues for longer periods, flexor tendons shorten. This cause increased difficulty in active or passive opening of the hand.16

Objective: Objective of the study was to examine the effects of Incentive Spirometry on cardiac autonomic functions in normal healthy subjects in 18-25 years age group.
Breathing exercise is defined as the therapeutic intervention by which there is purposeful alteration of a given breathing pattern.1 Breathing exercises are fundamental interventions for prevention and comprehensive management of acute or chronic obstructive pulmonary disorders, for patients who have undergone thoracic and abdominal surgical procedures, for patients with central nervous system deficit, for psychological conditions or for patients who are bedridden for extended period of time.2,3 It is known that the regular practice of breathing exercise (Pranayama) increases parasympathetic tone, decreases sympathetic activity, improves cardiovascular and respiratory functions, decreases the effect of stress on the body and improves physical and mental health.4 Pranayama has been researched mostly for its beneficial application in treatment of cardiovascular diseases,
Incentive Spirometry (IS), also referred as sustained maximal inspiration (SMI), is designed to mimic natural sighing or yawning by encouraging the patient to take long, slow, deep breaths by using a device that provides patients with visual or other positive feedback when they inhale at a predetermined flow-rate or volume and sustain the inflation for a minimum of 3 seconds.8,9 Studies have suggested that Incentive Spirometer is effective mean as prophylaxis and as part of intensive post-operative physiotherapy program following cardio-thoracic and abdominal surgeries, 10-13 for pulmonary hygiene with sickle cell disease and neuromuscular diseases, as well as a rehabilitation tool with COPD.14-16 Some of the proposed benefits of Incentive Spirometer are - subjects can assume responsibility for their own treatment without any harmful side effects, thus reducing the amount of direct patient contact time with therapist, 10 provision of prolonged phase of effective inspiration, more controlled flow and greater enthusiasm to practice, suitable to children and those with learning difficulties because it can be learnt by demonstration.17
Effect of Incentive Spirometry on Cardiac Autonomic Functions in Normal Healthy Subjects
Result: 3 months practice of Incentive Spirometry resulted in statistically significant change (p < 0.05) in following parameters - Basal heart rate, Immediate maximum heart rate, Steady state heart rate, Steady State heart rate (time in seconds) during heart rate response to Standing test; Minimum heart rate and Deep Breathing Difference (DBD) during heart rate response to Deep Breathing test.
ABSTRACT
Conclusion: 3 months practice of Incentive Spirometry changes autonomic function response.

The study was conducted at Padmashree Institute of Physiotherapy, Bangalore on 30 male and female undergraduate physiotherapy student volunteers. The inclusion criteria were: subject should be in the age group of 18-25 years, should be non-smoker and free from major health problems. Subjects who were unwilling or unable to complete the study or had cardiorespiratory problems or were practicing any form of regular breathing exercises were not included. Prior to participation, a written-informed consent was taken from all subjects and subjects were informed about study protocol. Ethical clearance for the study was obtained from the Institutional Ethical Committee, Padmashree Institute of Physiotherapy, Bangalore as per the ethical guidelines for Biomedical Research on Human subjects, 2001 ICMR, New Delhi.
Studies have proven that practice of pranayamic type of breathing exercises can produce significant effects on autonomic functions. Since, which is a SMI, is also one type of slow breathing exercises, similar results in terms of changes in autonomic response can be expected with use of IS-training. Therefore, there exists the need of the study to find out the effect of IS on cardiac autonomic functions. Therefore, this study was designed to assess the effect of IS on cardiac autonomic functions in normal healthy subjects in the age group of 18-25 years.
-Incentive Spirometer was held with one hand; other hand supporting the tube with mouth-piece which was inserted inside mouth.
The following cardiac autonomic function tests were performed following the procedures described by Banister and Mathias.4,18
The subjects were allowed to lie down for 5 min in supine position and ECG leads (GE Medical system MAC1200 ST) were connected. The basal heart rate was noted from the heart-rate counter in the polygraph. The subject was then asked to stand up immediately and changes in the heart-rate (HR) were recorded from the polygraph. The manoeuver was repeated 3 times at an interval of 5 min between each and the mean of three was taken for recording.
This was done with subjects in sitting posture with ECG leads attached to polygraph. The subject was asked to take a deep breath (deep inhalation followed by deep exhalation) and HR changes during these respiratory phases were recorded from the polygraph. This procedure was repeated for 3 times at 5 min interval and best of three was taken for calculation.
SUBJECTS AND METHOD
STATISTICAL ANALYSIS
PROCEDURE
The subjects were instructed not to practice any other physical exercise or yogic technique other than the prescribed one. Subjects were randomly assigned to Study group (n=15) and Control group (n=15). Autonomic function tests were performed before and 3 months after the study period for both groups.
-The subject was asked to sit relaxed on a chair.
The autonomic function test recordings were performed in the afternoon (between 2 and 5 pm) at the Padmashree Diagnostic Centre, Bangalore. The subjects were instructed not to take tea, coffee or any drinks 1 hour before and any food 2 hours before the recordings in order to exclude the effects of food and water intake on the recordings. Before performing the test, subjects were given enough rest of 15-20 minutes. Altogether, 30 subjects completed the study and there was no dropout.
Study group: Study group subjects were given training to learn and perform IS. The subjects were instructed to perform Incentive Spirometry (MediciserTM Respiratory Exerciser) for 10 repetitions every waking hour for 3 months.17
Data are mean ± SD

Data are mean ± SD; p-value < 0.05, Comparison of groups at baseline showed no significant difference.
Following HR-response to Deep Breathing, postscore Min HR was significantly more in Study group compare to post-score Min HR in control group. The variation of HR with respiration is known as Sinus Arrhythmia, which is generated by autonomic reflexes. Inspiration increases HR and expiration deceases HR i.e. during inspiration, vagal activity decreases and sympathetic activity increases. Opposite mechanism occurs during expiration.4,19 Thus, increase in Min HR during expiration in present study indicates that there may be predominance of sympathetic activity.
Following standing from supine position, subsequent HR changes are baroreceptor mediated which enhance sympathetic tone. 19 Therefore, significant increase in Steady State HR in Study group indicates that there may be improvement in sympathetic activity.Inthis
Previous studies have suggested that wellperformed slow, yogic breathing decreases sympathetic activity. 4,21-24 However, in this study, most of the variables of cardiac autonomic function tests were indicating marked increase in sympathetic reactivity. Possible reasons for obtaining this result may be as following:Inthis study, IS, which is considered as slow and sustained maximal inspiration, is performed for 10 repetitions per session without focusing on expiration. Previous study has shown that stimulation of carotid chemo- or baroreceptors can evoke reflex bradycardia, but such reflex effects are wholly or partly blocked during inspiratory phase of breathing by central neural inspiratory mechanisms and by the central actions of sensory nerves from the lungs.25
DISCUSSION
Additionally, hyperventilation resulting from slow and sustained maximal inspiration through Incentive Spirometer without focusing on expiration phase could be one of the possible mechanisms for getting sympathetic predominance response because hyperventilation is a powerful physiological stimulus and induces tremendous sympathetic stimulation.26
Indian Journal of Physiotherapy & Occupational Therapy. January-March 2013, Vol. 7, No. 1 267
Significant decrease in DBD following 3 months of IS-training in Study group indicates that there may be increase in sympathetic activity.
On immediate standing, HR increases and continues to rise for next several seconds.19,20 Following this, HR falls to minimum and then rises again to stabilize at Steady State HR.4 HR response to Standing assesses the integrity of parasympathetic cardiovagal function.19 In this study, post-score Imm Max HR was significantly more in Study group. However, it may be argued that the maximum increase in HR was more in Study group because their post-score Basal HR following 3 months of IS-training was more.
Test 1: HR response to Standing
Moreover, in this study, IS was performed via mouth. Some studies have suggested that because breathing mechanism (nerve innervation) is situated in the nose and not in the mouth; nose breathing becomes the function of parasympathetic nervous system.27 Studies done by Dr Douillard mentions that on a physiological level, nose breathing enhances deep breathing which contracts diaphragm and makes us breathe more efficiently by pulling more air into lower lobes of lungs. Chest breathing through mouth fill the middle and
The baseline data of the demographic and outcome variables did not show any statistically significant difference between the subjects in the Study and Control groups.

study, the stabilization of heart rate following the standing occurred in less time compare to its prestudy counterpart which indicates that there may be improvement in parasympathetic activity. Study done by G. K. Pal (2004) showed that Steady state HR (Time in sec) was reduced by more than 100 seconds to consider it as increased parasympathetic activity. 4 However, in this study, reduction in Steady State HR (Time in sec) within Study group and in between Study and Control groups were 1.36 sec and 2.84 sec respectively, which were negligible changes. Therefore, 30:15 ratio could be considered as more appropriate measure of parasympathetic function.21
Test 2: HR-response to Deep Breathing
In normal resting subject, Basal HR is the function of parasympathetic system.4 In this study, significant increase in post-score Basal HR in Study group indicates that the practice of IS may be improving sympathetic activity.

Limitations of the study were – small sample size, data collection from one place which may limit the generalizability of the findings, not performing IStraining under closed supervision of the therapist and autonomic function tests recording in afternoon time which may have influence on autonomic function.
Future recommendations are - conducting the study with larger sample size with inclusion of subjects from various sources under closed-supervised IS-training. There is further research scope to investigate effect of IS-training on pulmonary autonomic functions.

It is known that in addition to the primary organ dysfunction, impaired skeletal muscle performance is a strong predictor of low exercise capacity in subjects with severe COPD.4 Progressive decrease in functional activity and exercise performance in subjects with severe COPD is found. 5 The perception of the dyspnoea worsens with the sudden onset of high intensity constant work rate exercise. Further such dyspnoea is found to affect the activities of daily living (ADL).6 According to GOLD (Global Obstructive Lung Diseases) guidelines, the goals of clinical control in patients with COPD include Health Related Quality of Life (improved

Background: Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease associated with a high level of disability, the treatment of which is aimed at reducing symptoms, increasing function and improving the quality of life of the patient with lot of emphasis been given to the development of a Health Related Quality Of Life (HRQOL) questionnaire. St. George's Respiratory Questionnaire (SGRQ) is a self administered validated questionnaire used in COPD. The Clinical COPD Questionnaire (CCQ) was developed as a simple tool to help clinicians identify the clinical status of airways in individuals with COPD. Hence there is a need to validate the CCQ to identify the health status of those with COPD in Indian population.

Conclusion: CCQ can be considered at par with SGRQ to assess the HRQOL in individuals with COPD in South Indian population.
Results: Pearson correlation and Student's t-test were used for statistical analysis and it was found that the three individual components of CCQ correlated with those of the SGRQ (r =0.909, p<0.001).
Chronic Obstructive Pulmonary Disease (COPD) is the major cause of morbidity and mortality throughout the world. It is currently the 4th major cause of death in the world. The death rate from the disease has increased in the recent decades in apparent association with increase in cigarette smoking and air pollution.1
In India, about 5% males and 2.7% females above 30 years of age have been estimated to be suffering from COPD. There is a significant burden of COPD as a disease in the Indian community with overall prevalence of 6.85% in South India; with the prevalence of males being 7.4% and females being 4.64%.3

Data was analyzed by using SPSS 15.0, Stata 8.0, MedCalc 9.0.1 and Systat 11.0. Microsoft word and Excel were used to generate tables, graphs, etc. Statistical Method: Descriptive statistical analysis has been carried out in the present study. Results on continuous measurements are presented on Mean ± SD (Min-Max) and results on categorical measurements are presented
in Number (%).Significance is assessed at 5 % level of significance. Statistical Tests: Pearson correlation was performed to assess the correlation between the component scores and the total scores of CCQ and SGRQ. Student’s t-test has been used to find the significance of the correlation between the component scores and the total scores of CCQ and SGRQ.
Out of the 35 subjects, there were 29 males and 6 females. The scores of SGRQ – Symptoms component was a mean of 55.59 ± 24.93; Activity component was 66.32 ± 15.94; Impact component was 49.93 ± 18.39 and total scores were a mean of 53.69 ± 16.29(Table 1). The scores of CCQ – Symptoms domain was a mean of 3.11 ± 1.40; Functional state domain was 3.75 ± 1.08; Mental state domain was 2.91 ± 1.18 and total scores were a mean of 3.32 ± 0.99 (Table 2). The symptom component of CCQ had a good correlation with the symptom component of SGRQ (r=0.955, p<0.001); the functional state component of CCQ correlated well with activity component of SGRQ (r=0.821, p<0.001); the mental state component of CCQ correlated well with the impact component of SGRQ (r=0.886, p<0.001). The overall total score of 50 questions of SGRQ and the 10 questions of CCQ showed a very high correlation (r=0.909, p<0.001) (Table 3) and (Figure 3) .It takes a comparatively less duration of time to complete the CCQ as compared to SGRQ ( Table 4).

exercise and emotional function) and clinical goals (prevention of disease progression and minimization of symptoms).7 In recent years, a great deal of attention has been paid to developing and validating “quality of life” questionnaires for individuals with COPD, in order to identify and treat the functional as well as the emotional problems that are most important to those suffering from the disease.7Health Related Quality Of Life (HRQOL) has been defined as the “functional effect of an illness and its consequent therapy, upon a patient, as perceived by the patient”. HRQOL questionnaires allow the clinicians to measure directly the impact of the disease on an individual’s Activities of Daily Life.8 St George Respiratory Questionnaire (SGRQ) is a supervised, self administered, reproducible, valid and responsive instrument chosen as the gold standard to assess the HRQOL in Indian individuals with COPD. Clinical COPD Questionnaire (CCQ) is a self administered questionnaire specially developed as a simple tool to help clinicians identify the clinical status of airways in the individuals with COPD. Since the CCQ, which is a shorter and easier questionnaire, has not been validated for the Indian environment, the aim of the present study is to validate the CCQ and establish its effectiveness in comparison to the SGRQ, in South Indian population

An ethical clearance was issued from the institution prior to the study. A convenience sampling was done. It was a cross sectional study with 35 subjects inclusive of both males and females between 35 and 60 years of age, diagnosed with COPD(all stages according to GOLD standard) and having good English comprehension. Subjects with any neurological or orthopedic dysfunction, recent surgeries and other cardiopulmonary dysfunction were excluded from the study. The source of data collection was from M. S. Ramaiah Teaching Hospitals. On the day of the first session, the subject was handed out the SGRQ and asked to fill it up in the presence of the examiner. After two days, subjects were given the CCQ and asked to do the same. The scores of the individual components as well as the overall total were separately calculated for each of the questionnaires. Time taken by each patient for each of the questionnaires was also recorded using a stop watch.

The (CCQ) has been deemed as a valid and reliable tool to measure the Health Related Quality Of Life (HRQOL) in individuals with COPD and has been considered to be at par with the (SGRQ) in Netherlands, Italy and Sweden.7,8,9 The validation of a questionnaire is linked to the place and population where it is administered. SGRQ has been validated in the Indian population, but the CCQ has not been validated. SGRQ has been chosen as the gold standard as it is well validated, frequently used in COPD trials, it is available in Hindi and it was used in the original validation of CCQ.10 The overall total score of 50 questions of SGRQ

and the 10 questions of CCQ showed a very high correlation (r=0.909, p<0.001) (table 3 and figure 3).The individual components of CCQ significantly correlated with each of the components of SGRQ (table 3). Thus the CCQ can be considered at par with the SGRQ. Any increase in any of the components or the total of SGRQ would mean an increase in the corresponding component or total of CCQ. Both questionnaires have three components each. SGRQ, which has a total of 50 questions, is divided into symptoms component (8 questions), activity component (9 questions) and impact component (33 questions). It includes all possible questions that are asked in order to assess the overall status of the patient and the impact COPD has on people suffering from the disease. On the other hand CCQ has a total of 10 questions and is divided into three similar components – symptoms (4 questions), functional state (4 questions) and mental state (2 questions). CCQ has been developed by selection of potential questions that assess the quality of life of people suffering from COPD by experts in the field. Hence the 10 questions of CCQ include the important and relevant questions to be answered in order to assess the HRQOL in individuals suffering from COPD.8 From the present study, CCQ has shown a very high correlation with SGRQ. Hence it is apparent that CCQ can be used to assess the HRQOL in Indians who have COPD. Since this study has been done on a population of South Indians, it can be concluded that CCQ has a concurrent validity in South Indian population when compared to SGRQ. The CCQ takes a appreciably shorter duration of time to administer as there are only 10 questions to be answered as compared to the 50 questions of SGRQ. Thus CCQ has the added advantage of being easier and quicker to administer, thus can be used as a quick tool to assess the HRQOL of South Indians who have COPD.
There was a strong correlation between the St George Respiratory Questionnaire (SGRQ) and the Clinical COPD Questionnaire (CCQ); hence CCQ can be considered at par with the SGRQ in South Indian population. The CCQ is easy to score and allows data to be quickly collected. It is thus suitable for use in everyday practice for clinical trials or quality of care monitoring, of individuals with COPD, in South India.

Methodology: 80 independently ambulatory subjects (age group 50-70yrs) were randomly selected and divided into 2 intervention groups of 40 each. Task was to stand on the preferred leg with arms by side and one legged balance time was measured. Two sessions (1st & 2nd) of the task, of 5 days each, were given to subjects at a periodic gap of 30 days. Baseline and final measurements of one legged balanced time were compared after a three days practice intervention period.
All subjects are independently ambulatory without assistive device.
Age group: 50 to 70 years.
Results: Percentage improvement in balance time in both sessions was compared and statistical analysis was done by paired 't' test and 'z' test. All groups showed improvement, but Group II showed the most improvement in 2nd session, of 33.01% in males and 31% in female's resp. ('p' < 0.001). Comparison of percent improvement between Group I and II, showed an increment of 10% in balance time of group II in its 2nd session('p' < 0.001,HS).Thus showing that balance time increased significantly with physical practice interspersed with mental practice.

INTRODUCTION
ABSTRACT
Major concern of physical therapist is movement –its acquisition, quality and retention. Primary aim of physical therapist is to maximize patient’s movement potential. So focus is on physical techniques, for teaching new motor skills to patients.1 However it is not always possible to carry out task under guidance of therapist.Hence
A major concern of physical therapists with all patients, but especially with elderly, is balance. The increased postural sway seen with age is correlated
a.Inclusion Criteria
Purpose of study is: to compare "effect of only physical practice" with " effect of physical practice and mental practice" in subjects, for activity of one leg standing.
MATERIAL AND METHOD
Materials used: table, chair, cassette and record player, stop-watch, newspaper.
Conclusion: Our study concludes that Mental Practice along with Physical Practice may hence be an important therapeutic tool to encourage rapid acquisition of a motor skill.
Group I (n=40, 20 male s and 20 females) performed only physical practice in both sessions (1st & 2nd) and Group II, (n=40, 20 males and 20 females) performed only physical practice in 1st session and in 2nd session performed physical practice interspersed with mental practice. Mental Practice involved use of idealized visual and kinesthetic mental images provided to subjects through recorded tape.

FINDINGS
Percent improvement in balance time in both sessions was compared and statistical analysis was done by paired‘t’ test and ‘z’ test.
A short verbal health care history was taken.
An average of three readings of measured time was taken to have a baseline value on day 1. Group I & II subjects carried out physical practice of activity for next three days. Final value of balance time was taken from an average of three readings on day 5. On day 2,3,4: reading task was given, which distracted attention from original activity.

Imaging studies by Shadmer and Holcomb have shown cerebellum to be active during consolidation of a learned internal model of a task4. It acts as adaptive feed forward control system, which programs voluntary movement skills, based on memory of previous sensory inputs and motor outputs.
EFFECT OF PRACTICE
The comparison of percent improvement in Group I and II, showed an increment of 10% in balance time of group II in its 2nd session. Thus showing that the balance time increased with physical practice and mental practice of the activity.

Precision of one leg activity is enhanced by mental practice, which entails picturing of standing on one leg, while imagining kinesthetic feel of act and trying to balance on one leg and at the same time correcting imagined mistakes. This occurs in addition to actual physical performance of activity.

For Group 1 subjects, it can be inferred that, engram process is not strengthened as those subjects carried out an activity, not related to one leg standing, during reading session.

Materials and Methods: We recruited 60 healthy male volunteers by using convenience sampling with the mean age 20.5 ranges from 18-30 years. The subjects were divided into two groups based on their BMI (Group A BMI 18.5-24.9kg/m2and Group B BMI>25kg/m2 ). The spirometric test was done to measure Forced Vital Capacity (FVC), Forced expiratory volume in 1 second (FEV1), Slow Vital Capacity (SVC), Maximum Voluntary Ventilation (MVV) in sitting, right side lying and left side lying position, the values of three different positions were compared with in the groups and between the groups.
Results: FVC and FEV1 values show significant changes in three different positions in normal and obese subjects. The MVV of normal and obese groups in sitting, right side lying and left side lying was significantly varied. There was no significant difference in other values.
INTRODUCTION
ABSTRACT
Background and purpose: Body positioning is prescribed by Physical Therapists to directly enhance oxygen transport and oxygenation, to minimize the risk of aspiration, and to drain pulmonary secretion in most of the intensive care units. The aim of this study is to assess pulmonary function in sitting, right mid-prone, left mid prone position in healthy young adult subjects and to compare the effect of Body Mass Index (BMI) on pulmonary function in sitting, right and left mid prone position.

Body Mass Index (BMI) is a widely accepted and used index to measure obesity in both adults as well as in adolescents. Obesity can cause various deleterious effects to respiratory function, such as alterations in respiratory mechanics, decrease in respiratory muscle strength and endurance, decrease in pulmonary gas exchange, lower control of breathing, and limitations in pulmonary function tests and exercise capacity. These changes in lung function are caused by extra adipose tissue in the chest wall and abdominal cavity, compressing the thoracic cage, diaphragm, and lungs15. Many studies have stated that there is a direct relationship between lung function and body mass

index .Weight and body mass index as measures of overall abdominal adiposity are used as predictors of pulmonary function in many epidemiological studies. These measures are widely accepted as determinants of pulmonary function in many epidemiological studies6, 7. Abdominal adiposity may restrict the descent of diaphragm and limit lung expansion compared to overall adiposity, which may compress the overall chest wall.2Several previous studies have stated that increase in body weight decrease lung volume, but many studies have been small; they included subjects with coexisting morbidities8-10.Therefore, it is important to understand the relationship between body mass index (BMI) and lung
Keywords: Midprone Decubitus, Pulmonary Function Test, Body Mass Indices (BMI).
Conclusion: With right side and left side lying position the FVC and FEV1 values decreased significantly in compare to the sitting position, and there is no difference in lung volumes between normal and obese except MVV. MVV is significantly reduced in right and left side lying position. Upright sitting position will increase the lung volumes and capacities compared to the other positions.
The lung function parameters which were assessed by computerized spirometers were Forced Vital Capacity (FVC), Forced expiratory volume in 1second (FEV 1), Slow Vital Capacity (SVC), and Maximum Voluntary Ventilation (MVV)

STUDY PROTOCOL
side lying body positioning is prescribed by Physical Therapists to directly enhance oxygen transport and oxygenation, to minimize the risk of aspiration, and to drain pulmonary secretion in most of the intensive care units.11Compared with the upright position, recumbent positions have well documented deleterious effects on lung volume of the dependent airways, reduced flow rates ,and reduced arterial saturation .These effects are accentuated with age ,smoking history, obesity, breathing at low lung volumes, sedation and direct effects of anaesthesia12.
In recumbent positions gas exchange is improved with the healthy lung down in patients with unilateral lung disease and in right side lying in patients with bilateral lung disease. In patients with unilateral lung disease, the role of the inferior lung as gas exchanger and diffusion capacity is enhanced because of the cephalad displacement of the hemi diaphragm placing it in greater mechanical advantage.14The Effect of mid prone position on pulmonary function test among young adults of altered BMI has not been studied with the importance it deserves. This study aims to understand the relationship between the side-lying position and BMI on lung function.
The study was conducted at the Nitte Institute of Physiotherapy; the subjects were briefed about the protocol and the informed consent was obtained from them prior to the commencement of study. A detailed history regarding their habits, physical activity and history suggestive of any cardio respiratory or any systemic illness was elicited. The percentage of body fat was calculated by Quetelet’s Index15

Subjects
Body fat composition was measured was measured by the skin fold thickness method in the following manner, the skin fold thickness was measured at four different sites on the dominant side of the body by using skin fold callipers. Extremity skin folds were measured at the triceps, biceps, trunk, supra-iliac and sub scapular areas16, 17. The skin fold was picked up between the thumb and forefinger and the readings were taken 5 seconds after the calliper was applied. Three consecutive readings were taken and recorded at each site. The average of three readings at each site was calculated and sum of these values was entered into the table given by Durnin and Womersley18.to find out the body fat percentage. Body fat percentage and BMI of the subjects were compared to add weight age to the classification; high body fat percentage was seen to be associated with high BMI. The subjects were divided into 2 groups based on the GroupBMII30
Although side lying (mid prone) positions are commonly used clinically, the differential effects of right and left side mid prone position on lung function compared with a reference position such as upright sitting have not been studied in detail. There have been a few reports of improved arterial oxygenation in left versus right side-lying in patients with unilateral lung disease and bilateral lung disease and in patients following coronary artery bypass surgery.13

64subjects were selected for the study; the data collection of four subjects could not be completed. Statistical analysis was performed with SPSS software package. The mean age of the subjects who participated in the study was 20.5; range (18-30) .T-test compared the various positions in the two groups. Annova was used to compare the variables within the groups.
manoeuvre the subject performed thrice and the best of the 3 readings were selected. In each session the rest period was 15 minutes to accommodate the effects of position change on the pulmonary circulation, notably the pulmonary capillaries, which is time dependent.

FVC and FEV1 values showed significant changes in all three positions in normal and obese subjects (Table 1 & 2), (figure 1). But when we compared the values in between normal and obese groups in sitting position there was significant difference in MVV and no significant difference in other values (Table 3, figure 2).
Body position exerts a strong effect on pulmonary position, but its effect on the side lying position with undesirable Body Mass Indices (BMI) is still to be understood. This study investigated the interrelationships of PFT values in side lying positions between two different BMI groups. Studies previously done on this subject have shown marked improvement in patients who lay with the diseased or operated lung uppermost compared with the dependent position and many studies have concluded that obesity has a direct effect on pulmonary function. Fiona Manning et al
The clinical importance of our study is that since optimal lung function is seen in upright position, it can be beneficial if ventilator dependent patients are nursed in the upright position as opposed to the traditionally

Therefore the present study aims to assess the PFT values in sitting and side lying positions in young healthy population of different BMIs. We studied 60 healthy young adults in two different groups with three different positions. Our study findings confirm that FVC and FEV1 value was decreased in right side lying and left side lying when compared to the sitting position. The results of our study conform to the result of the previous study done by Fiona Manning et al19 and Behrakis et al 20. The decrease in FVC in recumbency may reflect both increased thoracic blood volume due to the increased venous return and cephalad displacement of the diaphragm caused by abdominal encroachment. Other factors which may have caused this decrease include increased airway resistance and decreased lung compliance secondary to anatomical difference between the left and right lungs and shifting of mediastinal structures. When the value between normal and obese subjects was compared, there is significant reduction in MVV in obese population. MVV is a measurement of respiratory muscle endurance, is reduced by 20% in healthy obese individuals and by 45% in obese individuals with obesity hypoventilation syndrome (OHS) 21. This may result from diaphragm dysfunction due to increased abdominal and visceral adipose tissue deposition. While other studies conducted by earlier authors have shown reduction in the lung volumes especially FRC and ERV, many researches proved that obesity (BMI>30) has a direct restrictive effect on pulmonary function. Wafaa R. AlBader et al22 proved that BMI>30 is associated with a restrictive effect on pulmonary ventilation. We selected subjects with BMI> 25, and the number of subjects with BMI>30 was very much limited; this may be the reason the other values are not significant in both the groups.
p-value (N=30)(N=30)
The major limitations of our study is we recruited normal subjects and we could have increased the number of subjects that would have given more statistical weightage, if we selected a diseased population that would have given more clinical validity of our study. The other components of pulmonary function tests could also have been done to further validate the study.

Materials and Methods: The QOL of 50 patients consisting of two groups were studied on two different occasions before phase II cardiac rehabilitation and after Phase II cardiac rehabilitation respectively by using SF-36v2 questionnaire.
Comparison of Quality of Life in off-pump Versus on-pump Coronary Artery bypass Graft (CABG) Patients
Coronary artery bypass grafting (CABG) is the major coronary artery revascularization procedure after any major vessel block. It is one of the landmark operations in the history of cardiac surgery that saved the lives of millions of people afflicted with coronary artery disease.1, 2 Coronary Artery Bypass Graft is a commonly performed surgery worldwide. In India around 500,000 CABGs are performed annually. CABG is the most accepted coronary revascularization procedure performed after a major vessel block3-5
There are 2 different methods of doing CABG: the traditional way, which is called the on-pump CABG, and the newer way, which is called the off-pump CABG (OPCAB). The pulmonary function after CABG is severely reduced; the reasons for the restrictive

impairment and atelectasis are multiple and include, besides the effects of anesthesia, intra-operative events such as internal mammary artery harvesting, changes caused by mechanical alteration of the thoracic cavity, immobilization and pain6. Roentgenologial signs of atelectasis are common and various studies have documented reduced lung volumes and oxygenation in the post-operative period7. Many studies show that the pulmonary complications are more in patients with on pump coronary artery bypass graft8
ABSTRACT
Background and purpose: Coronary artery Bypass Graft (CABG) is the commonly performed revascularization procedure after a major vessel block. Many studies have indicated that there is a reduction in Quality of Life after CABG. The aim of our study was to compare the Quality of Life (QOL) in off pump and on pump CABG patients before and after phaseII Cardiac rehabilitation and to find out the effectiveness of cardiac rehabilitation to improve the QOL.
Results: 50 patients with the mean age 47.9 years, (range 40-58) completed the study. Following the cardiac rehabilitation there was a marked improvement in the QOL of both the groups, and the physical and mental components scores in the SF-36v2 questionnaire were increased. The difference between the scores of off pump and on pump CABG was significant before phase II cardiac rehabilitation. After phaseII cardiac rehabilitation, there were no significant changes between the scores except for those of general health (p=.005), emotional role functioning (p<.001) and mental component score (p=.01)
before and after Phase II Cardiac Rehabilitation
Keywords: Quality of Life (QOL), off Pump CABG (OPCAB), on Pump CABG, Phase II Cardiac Rehabilitation.
All the patients underwent pre-operative chest physiotherapy to clear secretions and to improve the lung function. After surgery, the patients were divided in to two groups based on the type of surgery.
Phase II cardiac rehabilitation was a home-based individualized tailored program of aerobic exercises; preferably brisk walking17, 18. The exercises were taught to the patient in the department under physiotherapist supervision, and then the program protocol was given to the patient to be done at home for 3months. Patients were also trained in palpating the pulse and calculating the heart rate, and to rate the Rating of Perceived Exertion (RPE) of 11 to 14.The exercise program consisted of warm up which included breathing exercise, stretching exercise and gentle active exercise to upper limb, lower limb and trunk muscles for a period of 10 minutes, followed by graded aerobic training and cool down. Aerobic training was brisk walking for 3-5 times a week with intensity of 40-70% of Heart Rate Reserve (HRR) achieved in exercise test by using Karvonen formula, and RPE of 11-14 for duration of 20 to 40 minutes (ACSM guidelines 2005)19. Patients were contacted by phone every two weeks to ensure their interest in the program and to monitor the

No mortality was recorded in both the groups after extubation and all patients underwent phase I cardiac rehabilitation. The phase I cardiac rehabilitation included the physiotherapy techniques like incentive spirometry, coughing, huffing, chest manipulation, segmental expansion, thoracic mobilization and ambulation. Post operatively the exercises were started approximately 1 hr after extubation, and the patients were encouraged to perform all the exercises twice daily for the first 7 postoperative days.
STUDY PROTOCOL
METHOD
•Phase II – early post-discharge, duration up to 3
•Phasemonths.III
– supervised out-patient program including structured exercise.
•Phase IV – long-term maintenance of exercise and other lifestyle changes.
Group 1 – On pump CABG patients (n= 25).
After the phase I program the SF36-v2 questionnaire was administered. It consists of 36 short questions mirroring health and Quality of Life (QOL) in eight different aspects: bodily pain (BP, 2 items); mental health (MH, 5); vitality (VT, 4); social functioning (SF, 2); general health (GH, 5); physical functioning (PF, 10); and role functioning, both emotional (RE, 3) and physical (RP, 4). Role functioning reflects the impact of emotional and physical disability on work and regular activity. All the patients were explained about the questionnaire and asked to fill according to the questions.
Group 2 – Off pump CABG patients (n= 25).
Quality Metric’s SF-36V2 Health Survey asks 36 questions to measure functional health and well-being from the patient’s point of view. It’s called a generic health survey because it can be used across age (18 and older), disease, and treatment groups, as opposed to a disease-specific health surveys which focus on a particular condition or disease. The survey is meaningful to patients, clinicians, researchers, and administrators across the health care spectrum, and has various applications15.
This study was approved by the Central Ethical Committee of Nitte University. The patients posted for Coronary Artery Bypass Graft (CABG) were randomly selected from the cardiothoracic unit of K S Hegde Medical College with the permission of the cardiothoracic surgeon. We included subjects with isolated CABG, aged between 40-65 years and with Ejection fraction > 35% and we excluded the subjects with other than isolated CABG ,Age > 65 years, Myocardial infarction after CABG, Ejection fraction <35% , Renal failure and high risk subjects .
Subjects
Cardiac rehabilitation is divided into four phases, progressing from the acute hospital admission stage to long-term maintenance of lifestyle changes. According to American College of Sports Medicine (ACSM) 11, the rehabilitation phase can be divided into
Even reports on health economic aspects show that cardiac rehabilitation is a justifiable use of the healthrelated budget. However, access to cardiac rehabilitation is often limited12, 13, 14

One limitation of the study may be the sample size, since the less number will not give more statistical weightage. The phase II cardiac rehabilitation program was an individually tailored exercise program, in which the exercise frequency, intensity and mode were prescribed and the patient was encouraged to perform the exercise at home. The disadvantage of this type of exercise program is that it is non- monitored and thus compliance with the program cannot be ensured.

Overall QOL after surgical myocardial revascularization was fairly well preserved in both groups and comparable with that of a standard population in most aspects. General and mental health, vitality, physical and social functioning, and bodily pain were not negatively affected by surgery irrespective of the procedure chosen. The quality of life before the phase II cardiac rehabilitation in off pump and on pump patients was significantly changed; the QOL rating was more in off pump patients than on pump group. This may be due to CABG performed with cardiopulmonary bypass (CPB), also known as on- pump CABG, which has been associated with significant pulmonary complication and functional changes. Many of these abnormalities are thought to be caused by CPB. Duration of hospital stay and extubation period was lesser in off-pump group compared with on-pump group. The incidence of atelectasis and pleural effusion and ventilator support was significantly higher in on pump group. Four of the on pump patients were re- intubated during the phase I cardiac rehabilitation period. Many studies suggest that quality of life is better in OPCAB patients in the initial 2 weeks after surgery; our study revealed that quality of life can improve in both types of surgery after structured cardiac rehabilitation.
